See also Probit Ordinary Least Squares (POLS) .DefinitionThis is an econometric method intended as an easy alternative to the ordered probit analysis in the context of happiness economics. It is also usable for the estimation of a more-equation model with non-diagonal covariance matrix. Then it...
Instead, ordinary least squares regression takes those residuals and squares them, so they’re always positive. In this manner, the process can add them up without canceling each other. Statisticians refer to squared residuals as squared errors and their total as the sum of squared errors (SSE)...

Ordinary least squares regression (OLSR) is a generalized linear modeling technique. It is used for estimating all unknown parameters involved in a linear regression model, the goal of which is to minimize the sum of the squares of the difference of the observed variables and the explanatory vari...

the parameter vector is by definition a linear estimator, and if (II.II.1-10) then it follows that (II.II.1-11) Evidently, it follows from (II.II.1-11) that the parameter vector can only be unbiased if DX = 0 and if E(D*e) = 0. Now what happens to the covariance matrix ...
Definition 1 Given is a datasetD={(xi,yi)}i=1n, wherexi∈Rdrepresents the i-th feature (input) vector whileyi∈Ris its corresponding target (output) variable. Suppose that there exists an analytical model of the formf(x)=g∗(x,θ∗)+ϵthat is a generator of all observations fro...
The observed variables are histogram variables according to the definition given in the framework of Symbolic Data Analysis and the parameters of the model are estimated using the classic Least Squares method. An appropriate metric is introduced in order to measure the error between the observed and...
The other terms are vce(robust), but not vce(hc2) or vce(hc3), u = ( − x b)x and c is given by its regression-like definition. vce(hc2), u = √1 1 − ℎ ( − x b)x where c = 1 and ℎ = x (X′X)−1x ′. vce(hc3), u = 1 1 − ℎ ( − x...
