No need to apologize, welcome to the community. It is very good to have you
on board. There is a dedicated command in Stata that does contain the "bi"
in its name, -biprobit- which deals with two-equation probit models. So the
"bi" stems from the two-equation thing, not from the # of covariates...

Subject: st: Bivariate versus univariate definition
Line for server
Thank you in advance.
I have a very basic statistics question. I have just started using stata,
so thank you for your help.
My question concerns the definition of bivariate versus univariate.
When is one analysis considered bivariate, and when is another considered
univariate?
I have seen univariate describe tests involving 1 predictor and 1 output
variable, but aI have also seen them described as basically descriptive
statistics.
I have seen bivaraite used to describe Chi2 tests.
So what would I call logistic regression analysis involving only one
predictor variable, e.g. high mpg (see example below)? Univariate, or
bivariate analysis?
What would I call Chi2 test? Univariate, or bivariate analysis?
Thank you!
***BEGIN EXAMPLE
sysuse auto
generate highmpg=1 if mpg>=20
replace highmpg=0 if mpg
