Title stata.com egen functions may be used with egen, and conversely, only egen may be used to run egen functions. Depending on fcn(),

For example, to take the natural log of v1 and create a new variable (for example, v1_log), use: gen v1_log = log(v1) sysuse bplong, clear **Notice that gender-patient does not uniquely idenitfy our observations sort sex patient *Flag the row numbers where Stata sorted the "before" observations for each person gen flag_before1 = _n if when == 1 *Do the exact same sort as above sort sex patient *Again flag the row numbers where Stata sorted the "before" observations for each person this time gen flag_before2 I created a new variable from the mean of another variable using egen: egen afd_lr2 = mean(afd_lire2w) if ost == 0 Now I would like to replace the values with the mean of another variable if ost == 1: replace afd_lr2 = mean(afd_lireo) if ost ==1 This is not possible, as the mean function cannot be used with the replace command. Ofta när man jobbar med Stata använder man sig av en färdig datamängd, med data som någon annan har samlat in och sammanställt. Ibland samlar man själv in sin egen data, och ibland använder man sig av data som andra samlat in men som inte finns i Stata-format. egen var1 = mean(var2) Skapaenvariabelvar1somär medelvärdetavvar2. drop var1 var2 Tabortvar1ochvar2.

egen group(), label and encode do the same thing. We tend to use egen group(), label. See[D] egen and[D] encode. In the unlikely event that you have a noninteger categorical variable, use the egen solution. More likely, however, is that you need to read [U] 25.1.2 Converting continuous variables to categorical variables. Technical note The egen mean function makes creating means easy.

–generate-) or –egen-. In this post I will calculate an experience variable using a fictitious dataset. Consider the dataset shown in the figure below (Table 1).

Like generate, it is used to create new variables, but it is much more than that. Using egen difficult and tedious variables can be created easily. A number of more complex possibilities have been implemented in the egen command like in the following examples: egen nkids = anycount (pers1 pers2 pers3 pers4 pers5), value (1) egen v323r = rank (v323) egen myindex = rowmean (var15 var17 var18 var20 var23) bysort combined with gen/egen is probably one of the most useful command combinations when cleaning and creating outcomes. Notice that your data set will be sorted by all the variables (including those in parenthesis) you specify But you will create new variables by only what variables you specify outside the parenthesis Stata has some utility commands for creating new variables: The egen command is useful for working across groups of variables or within groups of observations. See[D] egen for more information.

egen. egen is the extended generate and requires a function to be specified to generate a new variable. In Stata we can state something as true like below: use egen agestandard = std(age) Stata only gives us this output to tell us the code ran correctly and there are no issues.

Okej, vi ska vara mest i Stata building (som jag beskrivet tidigare här). alla projektorerna eller så kan läraren visa något från sin egen dator.

Note that Python does not have value labels like Stata does.
