Chapter 5: Linear Least Squares Regression

In statistics, the residual sum of squares (RSS), also known as the sum of squared residuals (SSR) or the sum of squared estimate of errors (SSE), is the sum of the squares of residuals (deviations predicted from actual empirical values of data). It is a measure of the discrepancy between the data and an estimation model, such as a linear regression. A small RSS indicates a tight fit of the model to the data. It is used as an optimality criterion in parameter selection and model selection. WebNov 16, 2024 · Given a set of p predictor variables and a response variable, multiple linear regression uses a method known as least squares to minimize the sum of squared residuals (RSS):.
