To allow for variance heterogeneity, a variance-by-group structure was included if diagnostic plots and AIC values indicated violation of the residual homogeneity assumption (CRP and TNFα).
They must be broad enough to work across nations and regions, but flexible enough to allow for local variance.
To allow for unknown variance, previous research explored the performance of t-test statistics, coupled with a quantile substitution procedure for modifying the stopping boundaries, at controlling the familywise error-rate to the nominal level.
The first part is a small time period during which the base station is kept silent to allow for noise variance estimation at the receiver as it was already explained.
We intentionally selected high second moments for admission to allow for high variance.
Negative binomial models, which allow for the variance to differ from the mean, are often used to model count data when the data is found to be overdispersed [17].
Ongoing research includes porting the model to software that will provide estimates of parameter uncertainty as well as allow for nested variance structures.
Given a complex data with great variability in different treatments, i.e., overdispersion, the Poisson distribution with one free parameter is too simple to allow for the variance to be adjusted independently of the mean for such a data.
Current guidelines as we begin 2014 do not allow for much variance from the waiting periods mentioned above.
