In this paper D-optimal designs for the weighted polynomial regression model of degree p with efficiency function (1 + x 2)-n are presented. Interest in these designs stems from the fact that they are ...

The previous method may be more familiar to statisticians when different notation is used. A linear model is usually written The following example illustrates the programming techniques involved in ...

Assume that for i=1 to n, the ith measurement y i of the response y and the corresponding measurement x i of the vector x of p predictors are related by where g is ...

Polynomial and special function theory remains a vibrant area of mathematical research, interweaving classical algebra with advanced analysis. At its core, the study concerns algebraic expressions ...
