Hi All, As noted in large group/lab today, below are a few clarifications for the midterm:
Part
2, question e:
Purpose:
clean a string variable using the numeric assignments indicated.
Not
being asked to label missing (.); only
being asked to assign character values that are associated with missing data to missing.
Part
2, question i:
the question should be interpreted as follows: “Generate
a variable that indicates whether each participant ever seroconverted was HIV+…”
i.e.,
include patients who were HIV+ at baseline as “ever HIV+”. We should not have used the term "seroconverted".
Part 2, question i [RAE users only]:
for those of you using Stata on the RAE, IT has changed something to prevent Stata from accessing websites within RAE, which prevents you from downloading the user generated xfill command. For grading, you will need to write the code that answers the question, even though you won't be able to run it. You will need to comment out those lines of code (add a "*" in the beginning of the line) so that Stata doesn't throw an error and prevent the rest of the do-file from running. Thanks,
Crystal
