However, you can perform the test by following these steps: Estimate the model using OLS: Obtain the squared residuals, after estimating your model: Estimate the model using OLS: Examine the statistical significance of alpha using the t -statistic: The value of from estimating the regression Take the square root of the number you got in step 4. Three fundamentals of econometrics are worth remembering; First, the quality of the parameter findings depends on the current working condition of the economic model. An example of urban design managed particularly successfully due mostly to the Singaporean style of governance. If it is not, the researcher must either reject the hypothesis or make changes in the statistical model and start all over again. GMM generalizes the method of moments ( MM) by allowing the number of moment conditions to be greater than the number of parameters. The error term is assumed to follow some sort of statistical distribution.
