Dear all,
I am using pweights to analyse an unbalanced panel with survival analysis. I want to test the statistical difference of two survival curves, and I am using the cox option of sts test (the only available one with pweights. However, I don't understand why, according to the test, the observed number of events is 658.10 instead of 424 (_d == 424). Furthermore, how can the observed number of events be a number with decimals, as the cox test shows?
Thank you very much in advance.
Giovanni
