...t such that I can do it on a 400,000 row data set, I can do, for example, A[17,1]/A[17,2] #and I'll arrive at the mean number of modules per call where the call starts with a module that starts with 97. A[17,1] #is 10, which means that, out of every single call that started with a module of 97X,XXX, #they went through 10 modules in total. A[17,2] #is 6, which means that there was 6 calls in total that began with a 97X,XXX module. #Hence, A[17,1]/A[17,2] #is the average number of modules that were executed in all the calls that began with a 97X,XXX module. ----- ---- Isaac Resear...
