WebThe usual multiple linear regression model assumes that the observed X variables are fixed, not random. If the X values are are not under the control of the experimenter (i.e., are observed but not set), and if there is in fact underlying variance in the X variables, but they have the same variance, the linear model is called the errors-in-variables model or the …
