Let us run basic descriptive studies for the two variables we are interested in, utilizing the summarize command followed by the names from the variables (which can be omitted to summarize every little thing):
To check out a summary of the data files delivered with Stata form sysuse dir. To load the file we wish variety sysuse lifeexp (the file extension is optional). To check out what is actually within the file sort describe. (This command is usually abbreviated to only one letter, but I choose desc.)
Next a regression (or actually any estimation command) you may retype the command without having arguments to find out the effects once more. Try out typing reg.
You can resize or simply close Many of these windows. Stata remembers its configurations the next time it runs. You can also help save (and then load) named preference sets using the menu Edit
