ECON 452* -- Steps in an Econometric Research Project M.G. This will be important later on. It establishes a straightforward relationship between the independent and dependent variables. Constant communication about the progress is key to this step. The main tool of econometrics is the linear multiple regression model, which helps in estimating how a change in one of the explanatory variables affects the working of the model, from the variable being explained to the changes occurring on the dependent variable. Example: When basketball players are making several shots in a row and feel like they have a "hot hand" and can . Suppose population is 1M. In order to do so, applied econometricians would analyze economic metrics, try to find out if there are any statistical trends, and predict what the outcome would be for an economic issue.
