And many of them will be occurring at the same time as others too (overlap). Because applied econometricians acquire a closer experience with the data, they often face problems regarding data attributes that point to errors with existing set of estimation techniques and also alert their theoretical econometricians about the anomalies. It is also called a random (stochastic) variable. Step # 6: Attain associateship. Instead obtain the 2SLS-estimator in 1 step: 2. This is the fourth step and also the most important out of all. Specification of the econometric model of the theory .
