Technically speaking, the Individuals who are involved with econometrics are referred to as econometricians. Econometrics is the application of statistical methods to economic data in order to give empirical content to economic relationships. Steps Involved in Planning Process According to Koontz and ODonnell . For example, the model may try to differentiate the effect of a 1 percentage point increase in taxes on average household consumption expenditure, assuming other consumption factors, such as pretax income, wealth, and interest rates to be static. {\displaystyle \beta _{2}} Instead obtain the 2SLS-estimator in 1 step: 2. At this stage, econometricians would define variables found in the economic model and the relationship between different variables. It is used mainly, however, by economists to study relationships between economic variables. Econometricians test if this hypothesis will be true or not by using statistical models. However, the PhD by Research in Economics consultation helps with the selection of hypothesis with two simple steps they are.
