What Is SST in Statistics? Thesum of squares total(SST)or thetotal sum of squares (TSS)is the sum of squared differences between the observeddependent variablesand the overallmean. Think of it as the dispersion of the observed variables around themean—similar to thevariancein descriptive stati...
We can solve this problem using the formula: R2= SSR/SST Since we are assuming that R2= 1; then 1= SSR/SST which implies that SSR=SST, which is answer D. Note that we do not need to know the actual values of SSR and SST, but we ...
(2)the amount of variation in the observed values of the response variablethat is explained by the regression.(用回归估计出来的y) 引入以下三个评估参数: 对应图是: 评判标准: The coeffificient of determination, r 2, always lies between 0 and 1. A value of r 2near 0 suggests that the re...
you can compare the good ness-of-fit statistics in theTable of fits . Sum of Squares Due to Error This statistic measures the total deviati on of the resp onse values from the fit to the resp onse values. It is also called the summed square of residuals and is usually labeled asSSE...
