Sainmhíniú parameter estimation method in regression analysis based on minimising the sum of the squares of the residuals (a residual being the difference between an observed value and the fitted value provided by a model) made in the results of each individual equation Tagairt "Wikipedia > Least squares (16.10.2024)"
Nóta "More simply, least squares is a mathematical procedure for finding the best-fitting curve to a given set of points by minimizing the sum of the squares of the offsets (""the residuals"") of the points from the curve."
Sainmhíniú in variance analysis it is customary to regard the data as generated by a model(usually linear)consisting of certain class effects plus a stochastic component.When estimates are made of the class effects and subtracted from the observations,the residuals are estimates of the contribution from the stochastic component and the sum of squares of these residuals is known as the'error sum of squares',though'residual sum of squares'is preferable from many points of view Tagairt Kendall & Buckland,Dict.of Stat.Terms,1982
