Step 6: Hence, the solution for the given simultaneous equations is a = 3 and b = 0. Econometrics uses statistical methods after adapting them to the problems of economic life. The third step is to estimate the unknown variables of the model using economic data at disposal. This is done by statistical technique called regression analysis. Since the F statistic (2.38) is lesser than the F Table Value (8.845), we cannot reject the null hypothesis. When there are more moment conditions than parameters, the estimator is said to be overidentified. Estimate model using the data in Table 2.2 to get: Inspecting the dataobtain a printout or plot (graph) of the data Reason: to look for outliers An outlier is an observation that lies outside the range of the rest of the observations.
