Please explain what the term collinearity (or multicollinearity in the multiple regression context) means. Does it affect our regression estimates (i.e., betas) or their variances? If so, please explain how? Does multicollinearity affect the chances of making either a Type I or Type II error? If so, how so?

Briefly explain what perfect multicollinearity is and how it relates to what is often called the ”dummy variable trap”. This is where if you have multiple binary regressors (variables that are either 0 or 1) to represent a series of groups, you have to leave the variable that represents one of the groups out of the regression.
