Goals
- address colinearity of chemotherapy attitudinal measures
- investigate self-report measures of fun and performance during fMRI task
- incorporate above analysis into an individual differences regression

Results
6 variable model
- model
- Regression Coefficients = kills.damage + averTravel + CanRelDeath_pst + ChemoImpt_pst + ChemoGood_pst + ChemoVital_pst
- note
- This model is susceptible to collinearity between ChemoImpt_pst and ChemoVital_pst. Also possibble collinearity with ChemoGood_pst
5 variable model
- model
- Regression Coefficients = kills.damage + averTravel + CanRelDeath_pst + ChemoImpt_pst + ChemoGood_pst
- note
- This model is susceptible to collinearity between ChemoImpt_pst and ChemoGood_pst
5 variable model 2
- model
- Regression Coefficient = Performance + fmri_Fun + averTravel + CanRelDeath_pst + ChemoImpt_pst
Notes
lm(onset.2 + onset.3 ~ kills.damage + fMRIFun_pst + averTravel + CanRelDeath_pst + ChemoImpt_pst)
does not generate a stronger R squared than
lm(onset.2 + onset.3 ~ kills.damage + averTravel + CanRelDeath_pst + ChemoImpt_pst)
kills.damage is a better variable than Performance_pst
kills.damage does not correlate with Performance_pst, p ~ .8
Combined Chemo_score does not work well
Chemo_score = ChemoImpt_pst + ChemoVital_pst + ChemoGood_pst + ChemoPos_pst
Chemo_score = ChemoImpt_pst + ChemoVital_pst : 2 variable works slightly better than the 4 variable combination
- Question
- What does the hopelab behavioral study say about these measures.
