WebThe sample variance estimates $\sigma^{2}$, the variance of one population. The estimate is really close to being like an average. The numerator adds up how far each response $y_{i}$ is from the estimated mean $\bar{y}$ in squared units, and the denominator divides the sum by n-1, not n as you would expect for an average. What we would really like is for … WebFitting the Multiple Linear Regression Model. Recall that the method of least squares is used to find the best-fitting line for the observed data.

The root-mean-square deviation (RMSD) or root-mean-square error (RMSE) is a frequently used measure of the differences between values (sample or population values) predicted by a model or an estimator and the values observed.
