This article aims to learn the basic calculation process of least-squares means (LS means). I find it difficult to understand what LS actually means in its literal sense. The definition fromlsmeanspackage is shown blow, that have been transitioned toemmeanspackage. Least-squares means (LS means...
Least squares parameter calculation method, the programmable logic controller and its program by a programmable logic controllerPROBLEM TO BE SOLVED: To provide a method for calculating a least-square parameter from n data pairs with smaller arithmetic processing and storage amounts in a PLC.高橋 健...
A least-squares method of calculating phase shifts from the Bethe-Salpeter differential equation is presented. In order to avoid some difficulties in evaluating the stationary expression, the exact asymptotic form of the partial waves is approximated by an expansion involving the four-dimensional spheri...

θ^=(X′X)−1X′Y. It is assumed thatXhas rankp. If there is a linear dependence between the explanatory variables, we can select a linearly independent subset. The calculation of the inverse ofX′XisO(p2+δ),δ>0and if possible, one would seek to minimize the cost. IfX′Xis of...

[11] utilized the least-squares method to provide the initial iteration point, and then calculated the source position iteratively using the Geiger algorithm. Combining the least-squares method with the Geiger algorithm resulted in an increase of the source calculation speed. View article 22nd ...
Chapter 5 Least Squares The term least squares describes a frequently used approach to solving overdeter- mined or inexactly specified systems of equations in an approximate sense. Instead of solving the equations exactly, we seek only to minimize the sum of the squares of the residuals. The ...

Linear regression programs based on the least-squares method can readily be extended for weighted least-squares. 6.6.2.1 Heteroscedasticity Heteroscedasticity in data means that condition 5, about constancy of variance, is violated. In laboratory problems, nonconstancy of variance in measured data is ...
