In the generate command above, we used the tm() function, which lets us easily provide date values to Stata in string form; see [D] Datetime for more information about working with dates. If we wanted to check codes in more than one diagnosis variable, we could use a foreach loop or...

violin produces violin plots, a graphical box plot--kernel density synergism. The violin plot combines the basic summary statistics of a box plot with the visual information provided by a local density estimator. The goal is to reveal the distributional structure in a variable. Much like a tradi...

So how do I tell stata to generate a new indicator of "mothers" and to treat it as a property of mothers, not children? So that eventually I would extract moms from this raw data (e.g., keep ID BMI_M EMP_M if mom==1) and merge (1:many) it based on key variable (ID_fam)...

(1) noreplacement Unfortunately, the matching does not work that good. For example, I have a family firm patent from year 2000 but the matched non-family firm patent (identified with the new variable _id) is from year 2003, although it should be year 2000. The technology classes are ...
Taking the sp500 dataset, I show below that I can generate theone-perioddifference series for the level variable "close", with and withouttsset.Then I try to reverse-engineer to recover the level variable "close"from the difference series named "change", but I get stuck. ...
