Ordinarily a replica of twenty or so observations from a dataset is sufficient to display your dilemma. See help dataex for specifics. As from Stata fifteen.1 (and 14.two from 19 December 2017), dataex is included While using the official Stata distribution. Users of Stata 15 (or 14) need to update to get pleasure from this. Consumers of earlier versions of Stata need to put in dataex from SSC before they are able to utilize it. Kind ssc put in dataex as part of your Stata. The deserves of dataex are that we see your details as you do with your Stata. We see no matter if variables are numeric or string, whether you've worth labels defined and what's a consequence of a specific Screen format.
Which means For those who have a Mac laptop computer in addition to a Home windows desktop, You do not need two individual licenses to run Stata. You can put in your Stata license on any from the supported platforms.
Preferably the assignment to therapy groups could be randomized, as in a randomized controlled demo. To illustrate the strategies to appear, we initial simulate (in Stata) a large dataset which could come up inside a randomized demo:
Before you may make a map, you must set up a geography template. There are various freely obtainable here to suit your needs to put in and use.
