The least-squares method is practised to find a regression line or a best-fit line for the given model. Learn its definition along with plotting its graph and deriving its formula here at BYJU’S.

It is well known in a Random Effects Model, that the Best inhomogeneously LInear Prediction (inhomBLIP) of the random effects vector is equivalently generated by the standard Least-Squares (LS) approach. This LS solution is based on an objective function that consists of two parts, the first...
quantities, such as the observed value of a variable, and the expected value of that observation conditioned on the parameter value. Gaussian linear models are fit by least squares and least squares is the idea underlying the use of mean-squared-error (MSE) as a way of evaluating an ...

An example where wi is known is when each observation yi is really y¯i, the mean of ni repeated observations, so that V(y¯i)=σ2/ni and wi=ni. Most computer packages will fit models by weighted least squares with prechosen weights. However, weights often have to be estimated fro...
For least squares estimates, the average mean is a weighted average of the group least squares means that represents the overall mean at the neutral settings where the group least squares means are calculated. 对于最小二乘估计值,平均均值是组最小二乘均值的加权平均值,它表示中性设置(在此计算组...
