# Conditions for Inference for Regression-II

Learn about the normality of residuals and equality of variance in regression inference conditions.

## We'll cover the following

## Normality of residuals

The third condition is that the residuals should follow a normal distribution. Furthermore, the center of this distribution should be 0. In other words, sometimes the regression model will make positive errors —

The simplest way to check the normality of the residuals is to look at a histogram, which we visualize in the figure below.
