Chow predictive failure test
WebTwo possibilities are given in the question: u_t-squared and u_t. Recall that the formula for the variance of any random variable u_t is E[u_t - E(u_t)]squared and that E(u_t) is zero, by the first assumption of the classical linear regression model. Therefore, the variance of the random variable simplifies to E[u_t squared]. http://www.mkaranasos.com/EconmNot6ParamConst.pdf
