What can you say about the coefficient of X1 and value of y in the regression equation? <\/p>\n\n

y = \u03b20 + \u03b21\u2217X1 + \u03b22\u2217X2<\/p>\n\n

Consider the value of X1 changes from 0 to 1 and the value of X2 stays as 0 or a constant. Then, the value of Y would have changed by \u03b21 units given beta2 and X2 are constants.<\/p>\n"}

Consider you are performing multiple linear regression where X1 and X2 are independent variables and Y is the dependent variable.
