Binary explanatory variable
WebSuppose a response variable Y is binary, that is it can have only two possible outcomes which we will denote as 1 and 0. For example, Y may represent presence/absence of a certain condition, success/failure of some device, answer yes/no on a survey, etc. We also have a vector of regressors X, which are assumed to influence the outcome Y. WebQuestion: Let y be any response variable and x a binary explanatory variable. Let { (xi, yi): 1= 1, ..., n} be a sample of size n. Let no be the number of observations with x; = 0 and nthe number of observations with x; = 1. Let yo be the average of the y; with x; = 0 and yų the average of the vi with x; = 1. (1) Explain why we can write no ...
