Stata tag

Use the “Code Files” icon to attach your code file (s) to the Word document. Use the “Define Tags” icon to “tag” the output you want to insert in Word: Give the “tag” a name. Indicate whether it’s a value, table, figure, or verbatim output. There are two commands in Stata that can be used to take a random sample of your data set. Use the sample command to draw a sample without replacement, meaning that once an observation (i.e., case, element) has been selected into the sample, it is not available to be selected into the sample again. Categories: Statistics Tags: biostatistics, causal inference, estimation, gmm, IPW, treatment effects Rather, %21x is for use with Stata’s display command for those wanting to better understand the accuracy of the calculations they make.

randomtag requires Stata version 9 or newer.

Let’s use a file called autolab that does not have any labels. To have an output like that given from duplicates list, we use the duplicates tag command to create a new variable dup_id that assigns a 1 if the id is duplicated, and 0 if it appears once. Then we list those cases where dup_id is equal to 1. Stata has two built-in variables called _n and _N. _n is Stata notation for the current observation number. _n is 1 in the first observation, 2 in the second, 3 in the third, and so on.

By the way, if you intend to use more than 2-billion observations, be sure to click on help obs_advice that appears in the start-up notes after Stata egen is being parsed by Stata, and you can write extensions to it using Stata ado-code. You cannot do that with generate. This is a rather painful legacy of the 80s as compared to R where you can define a function inline and forget it after it was used.

(Stata interprets _N to mean the total number of observations in the by-group and _n to be the observation number within the by-group.) Having created the new variable dup, you could then . tabulate dup to see a report of the duplicate count. To base the duplicate count solely on name, type

EDIT: So then the id of tagged observations is just . by A B C: gen dup_id = id[1] For basic technique with by: see (e.g.) this discussion The helpful way to do that is with the -dataex- command, which you should install and always use when you show example data.

The state of an RNG corresponds to a spot in the sequence. The mapping is not one to one because there are more states than seeds. If you want to pick up where you left off in the sequence, you need to restore the state, as in the example below.
