1. if SSR = 25 and SSE = 20, what is R2 ?
2. If SSR = 47 and SSE = 12, what is R?
Please, do all the problems and show processes

11. From the fact that SST = SSR+SSE and the definition of R², explain what SSE must equal if R2 = 0. 12. Suppose we have the following regression model where x is a continuous variable and x2 is a binary variable where x2 = 1 for males and x2 = 0 for females: y = 10+2xı – 3x2 + 5x, x2 If the model is refit with females as the reference category for xy, write the new model equation.
In a regression analysis, if r2 = 1, then Select one: a. SSR = SST. b. SSE = SST. c. SSR = SSE. d. SSE = 1.
If SSR = 4 and SSE = 16, determine SST, then compute the coefficient of determination, 7, and interpret its meaning. SSTEN 2 = (Type an integer or a decimal. Do not round.) Interpret the meaning of 7. Choose the correct answer below. O A. It means that 1 - r of the variation in the dependent variable cannot be explained by the variation in the independent variable. O B. It means that r of the variation in the independent...
