Question restatement: Which of these are possible advantages of performing a log transformation of the response variable in regression modelling?\n\nOption 1: Ensuring that the errors have zero conditional mean. This is not a direct consequence of applying a log transformation to the response. The zero conditional mean is an assumption about the error term given the predictors in the regression model, not something ensured by transforming the response alone. Transformations can help wit......Login to view full explanation登录即可查看完整答案
