Bivariate regression assumptions
WebOn the other hand, the assumption for a parametric OLS regression model is that the residuals are normally distributed. In such a regression analysis, unless there is a very strong relationship ... Webat random from a fixed bivariate distribution—fixed in the sense that the same distribution is used for every precinct. (That replaces the “constancy assumption” of ecological regression.) The bivariate distribution is assumed to belong to a family of similar distributions, characterized by a few unknown parameters.
