XLSTAT version 2019.1.2
Our new version XLSTAT 2019.1.2 is now available.
Because our new maintenance release will allow you to access improvements, advanced options and increased performance, we recommend you update to our latest version.
Feature improvements
Linear regression (all XLSTAT-Solutions)
Mixed models (all XLSTAT-Solutions)
The Cholesky (Eskow & Schnabel) method has been integrated to deal with saddle points during the convergence of the Newton-Raphson algorithm.
Compute t-tests and F-tests for fixed effects using the Satterthwaite formula for denominator degrees of freedom. Appropriate for mixed models with unbalanced data or complex covariance structures.
It is now possible to choose between ordinary least squares or MIVQUE0 starting values for the Newton-Raphson algorithm.
Computations of random effects have been corrected.
