formula of ssr Take our Linear Algebra for Data Science in R to learn more about concepts like subspaces
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 Sum of Squares Regression SSR The sum of squared differences between predicted data points i and the mean of the response variable y

Using SSR and SST we can calculate R squared as R squared SSR SST For example if the SSR for a given regression model is 137 5 and SST is 156 then we would calculate R squared as R squared 137 5 156 The sum of squares SS is a statistic that measures the variability of a dataset s observations around the mean
First there are two broad types of linear regressions single variable and multiple variable In this exercise we focus exclusively on the single variable version A multi variable linear regression has multiple x variables Recently I wrote an article about Linear Regression and how it is used in Data Science
