m. In multicollinearity, the variances and the standard errors (Se) of the regression coefficient estimates will increase. This means lower t-statistics. The overall fit of the regression equation will be largely unaffected by multicollinearity. This also mean that forecasting and prediction will be largely unaffected. n. Regression coefficients will be sensitive to specifications. Regression coefficients can change substantially when variables are added or dropped.
