1. ### CI from normal distribution using indicator random variables

Suppose that {X_1,X_2,...,X_n} is a random sample from N(m,1). Let I_i be indicator random variables such that it is 1 if X_i <= 0 and 0 otherwise. Calculate the 95% confidence interval for m. Suppose that sample is large enough.

3. ### Survival Analysis: Cox Proportional Hazards with 4000 indicator variables

THE SITUATION: I am preparing a 420,008 observation Cox Proportional Hazards Regression model with 4001 indicator variables. The 4001st indicator is my baseline. I am using STATA to accomplish this task, but STATA/IC's maximum number of indicators it can generate is set at 2000. Further, the...
