Document Summary
In chapter 9, we made inferences about the means of one continuous random variable. In chapters 10 and 11, we made inferences about means for two or more groups. In chapter 13, we will look at statistical inference approaches aimed at relating two or more numeric variables. I = random error in y for obs i: the slope represents the change in y per one unit change in x, the y-intercept represents the value of. Y = annual sales (: suppose an new store will open and the size is 4000 square feet (x=4). What annual sales do you predict: estimating the regression parameters ( o and 1, sample linear regression equation. =i predicted value of y for obs i. Xi = the value of x for obs i: least squares criteria for estimating. 2 i i ny i n n i i.
