Thus !inlist() and !inrange() can be read as “not in list” and “not in range”. These functions can reduce your typing, reduce the risk of small errors, and make your Stata code easier to read and maintain.

So, when we said list if rep78 >= 4, Stata included the observations where rep78 was ‘ . ' as well. If we wanted to include just the valid (non-missing) observations that are greater than or equal to 4, we can do the following to tell Stata we want only observations where rep78 >= 4 and rep78 is not missing .

An egen function is dedicated to this task, tag(). This function tags just one observation in each group of identical values with value 1 and any other observations in the same group with value 0. . egen tag = tag(id) . tabulate npkg if tag Re: st: tag by category. Thank you very much!

The above code will tag one record for each combination of hospitalid and emrvendor. Stata provides support for many symbols in text in graphs, including both capital and lowercase forms of the Greek alphabet and many math symbols. You may already be familiar with the {char} tag—synonym {c}—which follows syntax 3 and Stata: tag all values in a group based on a characteristic of any values in the group Se hela listan på stats.idre.ucla.edu Stata allows you to label your data file (data label), to label the variables within your data file (variable labels), and to label the values for your variables (value labels). Let’s use a file called autolab that does not have any labels.

If you want a table showing each hospital and the number of vendors it uses, you were almost there: Code: egen flag = tag (hospitalid emrvendor) tab hospitalid if flag.

Stata functions, like functions in any similar language, fall on a continuum, from those you know you want to those you do not know you need. If you want a logarithm, a square root, or some probability function, the only small diﬃculty is likely to be checking the exact syntax Stata uses: Is log() equivalent to ln() or log10()?Howdo a list or range, by simply negating the function. Thus !inlist() and !inrange() can be read as “not in list” and “not in range”. These functions can reduce your typing, reduce the risk of small errors, and make your Stata code easier to read and maintain.

You don’t have to do anything to cause Stata to store these results, but if you’d like to use them, you need to know what they’re called. 2019-02-11 · Detect duplicate observations in a data set in Stata. You can check for duplicate observations in Stata in the following ways: The isid command can detect duplicate observations: .

The second command adds those values up by -country-. > Adding 1s, one for each instance, is usually just called counting. egen tag_emrvendor=tag(hospitalid emrvendor) bysort hospitalid: egen n_vendors=total(tag_vendor) But I can't make the frequency table which shows the number of vendors used per hospital 2) EMR functions that a different emrvendor is used per hospital char(128)displayed an invalid character symbol. Beginning with Stata 14, Stata’s display encoding is UTF-8 on all platforms. The char(128)function is an invalid UTF-8 sequence and thus will display a question mark. There are two Unicode functions corresponding to char(): uchar() and ustrunescape().
