Hi sir, I have been trying to use the asdoc command to create a frequency table where you could see how two groups vary through different weeks in regards to a binary variable. However I haven't found any documentation on how to do this. I have been trying to do it however I keep getting the error r(100). Saying something about ") required". I have checked the syntax and there's no parentheses missing. Would be very helpful to get some direction. Kind regards. MVM.
