The main contents include theoretical econometrics and applied econometrics. Theoretical econometrics mainly studies how to use, transform and develop mathematical statistics methods to make them a special method to measure economic relations.
Applied econometrics is to study the practicability of economic mathematical models or explore empirical economic laws with econometric methods under the guidance of certain economic theories and based on statistical data reflecting facts.
Extended data:
Two research objects of econometrics: cross-sectional data and time series data.
The former aims to induce whether different economic entities have similar behavioral correlations, and show the correlations through the estimation results of model parameters; The latter focuses on analyzing the data of the same economic actor at different times to show the dynamic behavior of the research object.
The emerging econometric research begins with the data of both cross-sections and time series, in other words, each cross-section has the observation value of time series at the same time, which is called panel data (or panel data analysis).
