From Stata: Access all the memory on your Mac; 64-bit now available

Stata for Mac can now take advantage of greater processing power and memory. 64-bit computers process larger blocks of information at a time and can directly address more memory than their 32-bit predecessors. Previously, only Stata for Windows and Stata for Unix used 64-bit capabilities, but now Stata for Mac does, too.

For exceptionally large datasets, the more memory you can access, the better. With 64-bit Stata software, you can maximize your 64-bit system's potential and say goodbye to the old 2-GB memory barrier imposed by 32-bit systems. You are limited only by the total amount of memory on your machine.

In addition to accessing more memory, Stata processes larger datasets more efficiently, making 64-bit Stata faster than 32-bit Stata.

For details, see What kind of performance increase can I expect in going from 32-bit to 64-bit Stata? and our list of supported platforms.

64-bit Stata for Mac includes Stata/IC, Stata/SE, and Stata/MP and requires an Intel-based Mac with a 64-bit processor and Mac OS X 10.5. Click here for how to determine if your operating system is 64-bit. Existing Stata 10 for Mac users can upgrade for free to 64-bit Stata for Mac by visiting

Stata for Windows and Stata for Unix users, contact us to obtain 64-bit Stata.

Need more speed and greater efficiency? Visit the Stata/MP pages for information about 64-bit computing on multicore or multiprocessor machines.

Stata Bookstore: The Workflow of Data Analysis Using Stata

Authors: J. Scott Long
Publisher: Stata Press
Copyright: 2009
ISBN-10: 1-59718-047-5

Pages: 379; paperback
Price: $52.00
Estimated ship date: November 24

Comment from the Stata technical group

The Workflow of Data Analysis Using Stata, by J. Scott Long, is a productivity tool for data analysts. Long guides you toward streamlining your workflow, because a good workflow is essential for replicating your work, and replication is essential for good science.

A workflow of data analysis is a process for managing all aspects of data analysis. Planning, documenting, and organizing your work; cleaning the data; creating, renaming, and verifying variables; performing and presenting statistical analyses; producing replicable results; and archiving what you have done are all integral parts of your workflow. Long shows how to design and implement efficient workflows for both one-person projects and team projects.

An efficient workflow reduces the time you spend doing data management and lets you produce datasets that are easier to analyze. When you methodically clean your data and carefully choose names and effective labels for your variables, the time you spend doing statistical and graphical analyses will be more productive and more enjoyable.

After introducing workflows and explaining how a better workflow can make it easier to work with data, Long describes planning, organizing, and documenting your work. He then introduces how to write and debug Stata do-files and how to use local and global macros. Long presents conventions that greatly simplify data analysis—conventions for naming, labeling, documenting, and verifying variables. He also covers cleaning, analyzing, and protecting your data.

While describing effective workflows, Long also introduces the concepts of basic data management using Stata and writing Stata do-files. Using real-world examples, Stata commands, and Stata scripts, Long illustrates effective techniques for managing your data and analyses. If you analyze data, this book is recommended for you.

Stata book news: A Gentle Introduction to Stata, 2nd Edition

Alan Acock’s A Gentle Introduction to Stata, Second Edition is aimed at new Stata users who want to become proficient in Stata. After reading this introductory text, new users will not only be able to use Stata well but also learn new aspects of Stata easily.

Acock assumes that the user is not familiar with any statistical software. This assumption of a blank slate is central to the structure and contents of the book. Acock starts with the basics; for example, the portion of the book that deals with data management begins with a careful and detailed example of turning survey data on paper into a Stata-ready dataset on the computer. When explaining how to go about basic exploratory statistical procedures, Acock includes notes that should help the reader develop good work habits. This mixture of explaining good Stata habits and good statistical habits continues throughout the book.

Stata for Macintosh FAQ: Copying graphs and tables on Macintosh

New from Stata FAQ:

Why am I unable to copy graphs and tables from Stata into other applications?
Title Copying graphs and tables on Macintosh  
Author Theresa Boswell, StataCorp
Date April 2008

Some users may experience problems with pasting graphs and tables from Stata to other applications.

Beginning with Stata 10 for Macintosh, Stata copies images to the Clipboard in the PDF format for the best possible output. However, some legacy applications such as Microsoft Office 2004 only support pasting of images from the Clipboard in the PICT format. This can cause problems for users who attempt to copy an image within Stata and paste the image to another application. If you are unable to copy images from Stata to your application, open the General Preferences dialog and check the Copy Images to the Clipboard as PICT checkbox.

The PICT format does not support rotated text and has been deprecated by Apple in favor of the PDF format. Rotated text in a Stata graph will appear horizontal on the pasted PICT image. If possible, we encourage you to upgrade the application to which you are pasting Stata output or graphs to one that supports Clipboard data in the PDF format, such as Microsoft Office 2008. Once you have upgraded your application, uncheck the Copy Images to the Clipboard as PICT checkbox in Stata so that Stata will copy images to the Clipboard in the PDF format for the best possible output.

now available: 2nd Edition of An Introduction to Survival Analysis Using Stata

From Stata News:

An Introduction to Survival Analysis Using Stata, 2nd Edition is now available

An Introduction to Survival Analysis Using Stata, Second Edition is the ideal tutorial for professional data analysts who want to learn survival analysis for the first time or who are well versed in survival analysis but not as dexterous in using Stata to analyze survival data. This text also serves as a valuable reference to those who already have experience using Stata’s survival analysis routines.

The second edition has been updated for Stata 10, containing a new chapter on power and sample-size calculations for survival studies and sections that describe how to fit regression models (stcox and streg) in the presence of complex survey data. Other enhancements include discussions about nonparametric estimation of mean/median survival, survival graphs with embedded at-risk tables, better hazard graphs through the use of boundary kernels, and concordance measures for assessing the predictive accuracy of the Cox model, as well as an expanded discussion of model building strategies including the use of fractional polynomials.

Stata Bookstore: Multilevel and Longitudinal Modeling Using Stata, 2nd Edition

Multilevel and Longitudinal Modeling Using Stata, 2nd Edition

Authors: Sophia Rabe-Hesketh and Anders Skrondal
Publisher: Stata Press
Copyright: 2008
ISBN-10: 1-59718-040-8
ISBN-13: 978-1-59718-040-5
Pages: 562; paperback
Price: $59.00

Comment from the Stata technical group

Multilevel and Longitudinal Modeling Using Stata, Second Edition, by Sophia Rabe-Hesketh and Anders Skrondal, looks specifically at Stata’s treatment of generalized linear mixed models, also known as multilevel or hierarchical models. These models are “mixed” because they allow fixed and random effects, and they are “generalized” because they are appropriate for continuous Gaussian responses as well as binary, count, and other types of limited dependent variables.

The second edition has much to offer for readers of the first edition, reading more like a sequel than an update. The text has almost doubled in length from the original, coming in at 562 pages. This second edition incorporates three new chapters: a chapter on standard linear regression, a chapter on discrete-time survival analysis, and a chapter resulting from an expanded discussion of random-coefficient and growth-curve models. The authors have updated this edition for Stata 10, expanding on discussions in the original edition and adding new in-text examples and end-of-chapter exercises. In particular, the authors have thoroughly covered the new Stata commands xtmelogit and xtmepoisson.

Comments from the Stata technical group

Using Stata for Principles of Econometrics, Third Edition, by Lee C. Adkins and R. Carter Hill, is a companion to the introductory econometrics textbook Principles of Econometrics, Third Edition. Adkins and Hill provide a quick introduction to using Stata’s menu system and command line before moving on to their many examples. Because the main textbook uses a learning-by-doing approach, this companion book is especially useful to get in more “doing”.

Using Stata for Principles of Econometrics, Third Edition, shows how to use Stata to reproduce examples from the main textbook and to interpret the output. The authors also provide important information needed to perform and understand econometric analyses.

Installing Stata 10 on Windows Vista

This is posted at Stata Support (

Some users may encounter the following error message when attempting to install Stata on a Windows Vista machine:

I cannot open C:\Program Files\Stata10\STATA.LIC for writing. No Action Taken.

The default Vista permission settings do not allow applications write permissions to their respective install directories, even if you are logged into a machine as administrator. Stata needs these permissions to create its license file.

To get around the problem, you must right-click on the Stata executable in the Stata install directory and select “Run as Administrator” from the right-click menu to open Stata. Then you can enter your authorization information, etc., and Stata will create the proper file.

See also here for solutions to update Stata on Windows Vista.
