Answer #1

Solution:

Residual Plot is used to test which of the following assumptions of linear regression.

A. The errors are independent.

since,

Linear regression is an analysis that assesses whether one or more predictor variables explain the dependent (criterion)

variable. The regression has five key assumptions:

Linear relationship

Multivariate normality

No or little multicollinearity

No auto-correlation

Homoscedasticity

There must be a linear relationship between the outcome variable and the independent variables. ...

Multiple regression assumes that the residuals are normally distributed.

Multiple regression assumes that the independent variables are not highly correlated with each other.
