This note demonstrates why regression coefficients and their statistical significance differ across degrees of data aggregation. Given the frequent use of aggregated data to explain individual behavior, data aggregation can result in misleading conclusions regarding the economic behavior of individuals. 关键词...
The data being used in regression analysis should be sampled in such a way that the samples are not dependent on any external factor. Random sampling can be tested using the residuals from the regression model. The residuals, which are an output from the regression model, should have no corre...

However, before we introduce you to this procedure, you need to understand the different assumptions that your data must meet in order for multiple regression to give you a valid result. We discuss these assumptions next.StataAssumptionsThere are eight "assumptions" that underpin multiple regression...
