[R] question on boot
Hello there: Dear Dr. Murdoch, I'm a statistician at Princess Margaret Hospital. Could you please help me with the bootstrapping? Can boot function (along with boot.ci) handle multivariate statistics? My intention is that I want to group the outcome data and evaluate the proportion of patients who are positive for a marker within each group. (i.e. I have two variables, a predictor and an outcome. The predictor is continuous and the outcome is binary. I want a statistic which groups patients based on the predictor variable (0-10, 10-20, 20-30, etc;) and check the proportion of patients who are positive for the outcome variable within each group).
