(Of course, you will have stored a copy of the dataset elsewhere, so this is not a serious problem.) If you are sure that you want to retain the original name of the variable with the recoded values, you may omit the gen option but the original values of the variable will be lost in this case. What follows after the comma causes Stata store the result in variable "industry_3". Here, 6/8 means "6 through 8" the boundaries (i.e. Let's assume that a a variable with eight categories is to be simplified by merging some of the categories: Normally, the recoded variable is not supposed to replace the original variable rather, you will add the variable with the recoded vlues to the data set under a different name. If you wish to change the categories of a variable, you may employ the command recode. Multiple Imputation: Analysis and Pooling Steps.Confidence Intervals with ci and centile.Changing the Look of Lines, Symbols etc.However,I realized after a bit that the top n wasn't the best approach for what the data I had and a better approach would be to actually eyeball the frequencies of all categories and display only those categories that had frequencies above a certain threshold. However, possibly because it does all of these together it takes considerably longer Groups offers more control since it lets you specify exactly how many values you want and whether its the most frequent or the least frequent categories.įre truncates the middle values and it did give me the 20 most and least frequent values. The groups and the fre user created modules both achieve this. Solution (thanks to /u/Aleksandr_Kerensky and /u/BasilVal) This largely a problem when the variable has more than 1200 categories, and running tabulate in this case will result in the too many values error. I'd rather not have to clear out the data every time I want to see the n most frequently occurring categories.

I am currently working with a rather large dataset that takes a fairly long time to load into memory even when I am running this on a high performance system. Is it possible for stata to show a frequency table of only the top n categories in a variable without using collapse?Ĭollapse is fine but it does clear the existing data in your memory. This is something I've wondered for a long time. Other users who have found the question cross-posted are encouraged to share the links as a reply as well.
