This is just the linear multiple regression model – except that the regressors are powers of X! Estimation, hypothesis testing, etc. proceeds as in the multiple regression model using OLS. The coefficients are difficult to interpret, but the regression function itself is interpretable Example: the TestScore – …

Hypothesis testing in multiple regression. 4.1 Introduction. In the proceeding sections we have studied in some detail regressions containing only one explanatory variable. In econometrics with its multitude of dependencies, the simple regression can only be a showcase. As such it is important and powerful since the methods applied to this case ...
