I am trying to merge the two datasets such that the new dataset should read as: id oid did x3 x1 1 1 1 5 . 1 1 2 6 . 1 1 3 6 . 1 1 4 6 . 2 2 1 6 12 2 2 2 6 12 2 2 3 6 12 2 2 4 6 12 3 3 1 6 13 ...
It is possible that -tsappend- will take long time on a large dataset. -tsappend- is ado-code and with unbalanced data, it needs to loop through each panel in your dataset, which might take a while. I believe that Stata is not hanging, it's just taking a while to do the task th...
Multiple-key merges arise when more than one variable is required to uniquely identify the observations in your data. In Merging data, part 1, I discussed single-key merges such as . merge 1:1 personid using ... In that discussion, each observation in the dataset could be uniquely identi...
It turns out that despite having been advertised as datasets for a single subject, there were observations mixed in from some of the other subjects into the problem datasets. I had simply read each subject's dataset into Stata and ran a describe but had not checked the claim that each datas...

Hello, I appended to my master dataset a dataset in which a couple of variables (existing also in master as byte) are formated as string. Stata produces no error but solely a note (note: hzlokal is str1 in using data but will be byte now). However, it does not append any data ...
have the same names -- little point in -append-ing otherwise -- it is difficult to think of a work-around other than having unique variable names in each dataset, to each of which you attach -notes-. I haven't tested that. A clumsier alternative is to store text in a string ...
