Because many applications of regression in the social sciences involve analysis of causes randomly drawn from a larger population, some of the major examples are constructed to show more clearly the properties of regression estimates derived from samples. The concepts of bias and efficiency in statistical estimation receive particular attention.

A fitted linear regression model can be used to identify the relationship between a single predictor variable x j and the response variable y when all the other predictor variables in the model are "held fixed". Specifically, the interpretation of β j is the expected change in y for a one-unit change in x j when the other covariates are held fixed—that is, the expected value of the partial.

In statistical modeling, regression analysis is a set of statistical processes for estimating the relationships among variables.
