Question

Which of the following should be used to assess the collinearity among explanatory variables condition. (Select all that apply)

a residual plot of the residuals versus predicted values

a scatterplot matrix

a correlation matrix

a normal probability plot of the residuals

Definition Definition Relationship between two independent variables. A correlation tells the degree to which variables move in relation to each other. When two sets of data are related to each other, there is a correlation between them.

Which of the following scatter plots that true linear association?
Which of the following are true? (Select all that apply.) 1 An assumption of a linear regression is a consistent dispersion of the observations from the regression line. 2 An assumption of a linear regression is that the residuals form a normal distribution. 3 Omitted variable bias is when you don’t include the dependent variable.
