Simple linear regression is commonly used in forecasting and financial analysis—for a company to tell how a change in the GDP could affect sales, for example.

The most basic regression relationship is a simple linear regression. In this case, E( Y | X ) = μ ( X ) = β 0 + β 1 X , a line with intercept β 0 and slope β 1 .

For example, you might use regression analysis to find out how well you can predict a child's weight if you know that child's height. The following data are from a study of nineteen children. Height ...

A standardized regression coefficient is created by transforming all variables in the model to have a mean of zero and a standard deviation of 1.0. This allows the standardized coefficients to be ...

Simple linear regression relates two variables (X and Y) with a straight line (y = mx + b), while nonlinear regression relates the two variables in a nonlinear (curved) relationship.

Simple linear regression analysis is concerned with describing the linear relationship between a dependent (outcome) variable, y, and single explanatory (independent or predictor) variable, χ ...

Course TopicsLinear models, generalized linear models, and nonlinear models are examples of parametric regression models because we know the function that describes the relationship between the ...
