Mathematically, SST = SSR + SSE. The rationale is the following: the total variability of the data set is equal to the variability explained by the regression line plus the unexplained variability, known as error.
How are SST, SSR, SSE and RSS related?
Simply remember that the two notations are SST, SSR, SSE, or TSS, ESS, RSS. There’s a conflict regarding the abbreviations, but not about the concept and its application. So, let’s focus on that. How Are They Related? Mathematically, SST = SSR + SSE.
Which is better SST or SSR or SSE?
Mathematically, SST = SSR + SSE. The rationale is the following: the total variability of the data set is equal to the variability explained by the regression line plus the unexplained variability, known as error. Given a constant total variability, a lower error will cause a better regression.
Which is the correct sum of SSE and SSR?
SSE is the “error sum of squares” and quantifies how much the data points, , vary around the estimated regression line, . SSTO is the “total sum of squares” and quantifies how much the data points, , vary around their mean, . Note that SSTO = SSR + SSE. The sums of squares appear to tell the story pretty well.
