Intuition suggests that altering the covariance structure of a parametric model for repeated-measures data alters the variances of the model's estimated mean parameters. The purpose of this article is ...
The BLOCKS statement finds a design that maximizes the determinant |X'AX| of the treatment information matrix, where A depends on the block or covariate model. Alternatively, you can directly specify ...
You can use covariance and contravariance to provide polymorphic extension to delegates, arrays, and generics in C#. Here’s how. The C# programming language provides support for variance in two ways: ...
