Herein, there is no need to choose an appropriate variance manually.
The excitation noise is generated with the appropriate variance so that the channel vectors are WSS.
In such settings, appropriate variance adjustments must be made in order to estimate the sufficient sample size correctly.
Whilst the appropriate variance function may be identified from the modified Park test, one obtains different regression coefficients and inferences on incremental/marginal effects as the link function selected varies.
By modelling the residual variance per cluster through an appropriate variance structure (i.e., the varIdent structure) we were able to account for this variability in the data, which resulted in a model with smaller standard errors for the parameter estimates as compared to the other tested models (Table 1).
H R t) was compared to 1 by the Wald's test with the appropriate variance according to the models.

Mixed models are also useful to account for the autocorrelation of residuals over time and hints are given for the selection of an appropriate variance-covariance structure.
In order to evaluate the average behavior of our transmission strategies for different realizations of the channel coefficients, we will model the entries of Ht,h11,H12 ,h21 and H22 as samples from independent circularly symmetric Gaussian processes with zero mean with appropriate variances.
The appropriate variance-covariate structure was determined using AIC scores in conjunction with residual plots for model developed using REML.
εi,j,t represents normally distributed residual errors, including the appropriate variance-covariance matrix to describe spatial correlation at the patch level.
However, severe heterogeneity of variance in the initial linear regression models required the application of a generalised least squares extension to determine appropriate variance-covariate terms and meet the assumptions of homogeneity of variance [[42], [44], see Text S3].

Since I tried Ludwig back in 2017, I have been constantly using it in both editing and translation. Ever since, I suggest it to my translators at ProSciEditing.
