Fortunately, one of the primary contributions of econometrics is the development of techniques to address such problems or other complications with the data that make standard model estimation difficult or unreliable.The following table lists the names of the most common estimation issues, a brief definition of each one, their consequences, typical tools used to detect them, and commonly accepted methods for resolving each problem. By Roberto Pedace . You can use the statistical tools of econometrics along with economic theory to test hypotheses of economic theories, explain economic phenomena, and derive precise quantitative estimates of the relationship between economic variables. The ordinary least squares (OLS) technique is the most popular method of performing regression analysis and estimating econometric models, because in standard situations (meaning the model satisfies a series of statistical assumptions) it produces optimal (the best possible) results. In some cases, you have to perform these calculations by hand (sorry). You can use the statistical tools of econometrics along with economic theory to test hypotheses of economic theories, explain economic phenomena, and derive precise quantitative estimates of the relationship between economic variables. To accurately perform these tasks, you need econometric model-building skills, quality data, and appropriate estimation strategies. The proof that OLS generates the best results is known as the The model parameters are linear, meaning the regression coefficients don’t enter the function being estimated as exponents (although the variables can have exponents).The values for the independent variables are derived from a random sample of the population, and they contain variability.The explanatory variables don’t have perfect collinearity (that is, no independent variable can be expressed as a linear function of any other independent variables).The error term has zero conditional mean, meaning that the average error is zero at any specific value of the independent variable(s).The model has no heteroskedasticity (meaning the variance of the error is the same regardless of the independent variable’s value).The model has no autocorrelation (the error term doesn’t exhibit a systematic relationship over time).If one (or more) of the CLRM assumptions isn’t met (which econometricians call After you acquire data and choose the best econometric model for the question you want to answer, use formulas to produce the estimated output.
