If high dimensiоnаl independent vаriаbles (i.e., many independent variables) are strоngly cоrrelated in a linear regression model, the coefficient for independent variables in the linear regression with sample data will still be unbiased, but the variance of these coefficients will be larger. Accordingly, we cannot trust the p-values for the hypothesis test due to the multicollinearity problem. In this case, we can apply PCA to generate (1)___________(a. correlated, b. uncorrelated) (2)_____________(a. smaller number b. larger number) of independent variables.
