The assignment focuses on conducting a regression analysis to examine the relationship between changes in a variable, represented by 'change_sqrt_u', and Beck Depression Inventory (BDI) scores measured at two different time points (T1 and T2). The output includes correlation coefficients, covariance values, collinearity diagnostics, and residual statistics. These results provide insights into the strength of the linear relationship between the variables and can be used to understand how changes in 'change_sqrt_u' might influence BDI scores over time.
