For 5 pairs of observations the following results are obtained X=15, Y=25, X2 =55, Y2 =135, XY=83 Find the equation of the lines of regression and estimate the value of X on the first line when Y=12 and value of Y on the second line if X=8. Establishing an Econometric Model In Regression Analysis There are two basic approaches to estimating models of energy and nonfuel-mineral demand. The purpose is to use statistical modeling and analysis in order to transform qualitative economic concepts into quantitative information that individuals can use. Supply and Demand is one of the first things we learn in economics.

This guide demonstrates how to use EViews to complete the econometric analysis illustrated in the text. Third, the parameter estimates have a very slim chance of being on similar lines with the actual parameter values that are generated by the statistical data, even if the econometrician identifies the process as the source of the original data. It is in this second step that we will use Lagrange multipliers. Some of the most important methods of economic analysis are as follows: 1. Three fundamentals of econometrics are worth remembering; First, the quality of the parameter findings depends on the current working condition of the economic model. ; ; Lets explain decision tree with examples. . {\displaystyle \beta _{2}} Identify a list of potential variables/features; Both independent (predictor) and dependent (response) Gather data on the variables; Check the relationship between each predictor variable and the response variable. 3.

Say, for example, qualifications, experience and skills are the factors that affect productivity of a person and therefore the remuneration. This step is necessary because a regression tends to estimate the marginal impact of a specific explanatory variable after taking into account the variance caused by the impact of the other explanatory variables to the model.
