WebFeb 22, 2024 · 1. Sum of Squares Total (SST) – The sum of squared differences between individual data points (y i) and the mean of the response variable (y). SST = Σ(y i – y) 2; 2. Sum of Squares Regression (SSR) – The sum of squared differences between predicted data points (ŷ i) and the mean of the response variable(y). SSR = Σ(ŷ i – y) 2; 3. The total sum of squares is a variation of the values of a dependent variable from the sample mean of the dependent variable. Essentially, the total sum of squares quantifies the total variation in a sample. It can be determined using the following formula: Where: 1. yi – the value in a sample 2. ȳ – the mean value … See more The regression sum of squares describes how well a regression model represents the modeled data. A higher regression sum of squares indicates that the model does not fit the data well. The formula for calculating the … See more The residual sum of squares essentially measures the variation of modeling errors. In other words, it depicts how the variation in the dependent variable in a regression model cannot be explained by the model. Generally, a lower … See more
