1)If a linear model is correct, then a least squares fit is unbiased. Knowing that, why would one want to use some form of penalized regression

2) Define the AIC criterion for logistic regression

3) continued) In the context of logistic regression, describe forward stepwise selection based on the AIC criterion.

Use the least squares method to fit a simple linear model that relates the salary (dependent variable) to education (independent variable). a- What is your model? State the hypothesis that is to be tested, the decision rule, the test statistic, and your decision, using a level of significance of 5%. b – What percentage of the variation in salary has been explained by the regression? c – Provide a 95% confidence interval estimate for the true slope value. d -...
