Consider a regression study involving a dependent variable y, a quantitative independent variable a2, and a categorical independent variable with two levels (level 1 and level 2). a. Write a multiple regression equation relating az and the categorical variable to y. 1. E(y) = Bo + B11 2. E(y) = Bo + B2x2 3. E(y) = Bo + B,e1 + 92 4. E(y) = Bo + Bi a + Bza2 Option 4 Enter the values of dummy variable ai that are used to indicate the two levels of the qualitative variable. If your answer is zero, enter "0". Level 1 Level 2

Transcribed Image Text:Consider a regression study involving a dependent variable y, a quantitative independent variable a2, and a categorical independent variable with two levels (level 1 and level 2).
a. Write a multiple regression equation relating æz and the categorical variable to y.
1. E(y) = Bo + Bia1
2. E(y) = Bo + B2a2
3. E(y) = Bo + Bieı + 82
4. E(y) = Bo + Bia1 + B22
Option 4
