چکیده
What do we mean by econometrics? Econometrics is the field of economics in which statistical methods are developed and applied to estimate economic relationships, test economic theories, and evaluate plans and policies implemented by private industry, government, and supranational organizations. Econometrics encompasses forecasting–not only the high-profile forecasts of macroeconomic and financial variables, but also forecasts of demand for a product, likely effects of a tax package, or the interaction between the demand for health services and welfare reform.

متن کاملForecast of Iran’s Electricity Consumption Using a Combined Approach of Neural Networks and Econometrics
Electricity cannot be stored and needs huge amount of capital so producers and consumers pay special attention to predict electricity consumption. Besides, time-series data of the electricity market are chaotic and complicated. Nonlinear methods such as Neural Networks have shown better performance for predicting such kind of data. We also need to analyze other variables affecting electricity c...
