# Perform some exploratory analysis on the DTS study described above. (a) Compute the mean and standard deviation

## Question:

Perform some exploratory analysis on the DTS study described above.

**(a)** Compute the mean and standard deviation of the HamD scores for the two treatment groups at each time point.

**(b)** Treat repeated outcomes in HamD scores as if they were independent and fit the linear model with treatment and measurement time (as a continuous variable) as well as their interaction as the predictors. Is DCM, compared with CAU, more effective in treating depression?

**(c)** Treatment stigma (TS) scores take values \(0-3\), with higher scores indicating more negative stigma. Compute the proportions of each level of TS scores for the two treatment groups at each time point.

**(d)** Treat repeated outcomes in TS scores as if they were independent and fit a cumulative logistic model with treatment and assessment time (as a continuous variable) as well as their interaction as the predictors. Is DCM, compared with CAU, more effective in treating stigma associated with depression treatment?
