"Witryna7 cze 2015 · You are logging your dependent variable, which means that observations where the dependent variable is equal to zero are dropped. Therefore, dummy variables that are equal to 1 only when the dependent variable is zero will be identically zero in the sample used in the estimation. These will, of course, be dropped because of collinearity. " - Imtest is only possible after regress

Witryna15 sie 2024 · The test dataset, as the name suggests, is only used for evaluation/testing your model. Your task is to produce the predictions for the test data, by learning a model through the training dataset. During training you use the given annotations/labels (what you refer to as 'response variables') of the training dataset to fit the model. Witryna10. I found an R function that does exactly what you are looking for. It gives you robust standard errors without having to do additional calculations. You run summary () on an lm.object and if you set the parameter robust=T it gives you back Stata-like heteroscedasticity consistent standard errors.

Witryna16 paź 2024 · It refers to the variance of the error terms in a regression model in an independent variable. If heteroscedasticity is present in the data, the variance differs across the values of the explanatory variables and violates the assumption. This will make the OLS estimator unreliable due to bias.
