| hizmo | This is a stupid question. Multiple regression is when parameters >= 2. Since 2 >= 2 and question refers to " a multiple linear regression equation" |
| adidas | No hizmo. Here is a linear regression equation: Y = 1X + 2Z + 3M + 4N. 4 parameters! So you need to know the number of independent variables and parameters. |

| jsc298 | I think the point is that multiple regression implies at least two independent variables, so there are a minimum of three parameters. |
