Sentence examples for specify the variance from inspiring English sources
Second, the performance of filtering drops off when we incorrectly specify the variance of the sampling error, and especially when we overestimate it.
To specify the variance equation to model volatility presence in differenced logarithmic exchange rates (i.e., exchange rate returns), we used five different GARCH family models, each of which has a different purpose.
Scientists must also specify the variance of each of the repeated measurements.
This matrix was used to specify the variance structure in a multivariate generalized linear model.
Once the goals and the variables are specified, the next step is to specify the variance and correlation patterns among the repeated measures.
In contrast, our Theorem 1 provides several closed-form expressions which specify the variance-to-mean relationship for all the members of the Poisson-Tweedie family (left {{mathcal {P}}{mathcal {T}}_{p, mu, lambda }, p geq 1, mu in Omega _{p}, lambda in mathbf {R}_^{1} right }) introduced by formula (3).

Mechanistically, assumptions of random-effects models are: (1) the random effects are distributed normally with mean equal to 0 and unknown variance, (2) within-group correlation is constant through time, and (3) the analyst has correctly specified the variance-covariance structure (see [39] for a review of the application of random-effects models in resource selection analysis).
