What is Multicollinearity?. Multicollinearity is the condition where the independent variables are linearly related to each other. Variables need not be causally related, only correlated.X's are usually related to some extent, it is a matter of degree.. Perfect Multicollinearity. Recall to estim

The Problem of Heteroskedasticity. Autocorrelation is one of two possible violations of our assumption E(ee')=s2InSpecifically, it is a violation of the assumption E(et,et-1)=0Coefficients are unbiased, but standard errors and t-tests are wrong.Generally, standard errors are TOO SMALL. Patterns

Statistical Significance of CoefficientsT-testsSubstantive Size of EffectsGenerate predictions from the modelSize of ResidualsCompare to substantive effectsForecasting Out-of-Sample. 3. Statistical Significance of Coefficients. First thing we want to do with a model is see if the coefficients relevant for our theory are discernable from zeroT-tests give us confidence that relationships we observe are generalizableDon't get too focused on .05 as a
