There was a post once upon time dealing with the differences of multivariable and multivariate regression. I have seen the relevant post here. However I am having this debate with a colleague and while I agree with the information of this post, my colleague insist that multivariable regression is actually just multivariate regression. The definitions of this individual are :
- multivariate regression: one end point, multiple linear predictors
- multivariate multiple regression: multiple endpoints and multiple linear predictors.
Whereas I think the definitions are:
- multivariable multiple regression: one endpoint, multiple linear predictors
- multivariate multiple regression : several endpoints, several linear predictors.
So, is this all a matter of semantics? Are they the same thing? Why does there need to be a distinction for multivariable and multivariate if one kind of is a subset of the other?
