Sentence examples for a variance parameter from inspiring English sources

A general equation for a variance parameter, appearing as a crucial quantity in a simple algebraic expression for the mean chemical rate, is derived.

The spread coefficient is a variance parameter in the nonlinear transfer function in an RBF network and can be set as a multiple of the average distance between data points considered in the fitting process [18].

In general, sample sizes of at least 30 observations are recommended when applying the central limit theorem to the sampling distribution of a mean [8]; when dealing with a variance parameter as target, probably 50 should be the minimum number of paired observations since estimating second moments (like the variance) is more prone to uncertainty than estimating first moments (like the mean).

The number of seeds each plant produces increases linearly from minimum possible seed production to its maximum; the generated seeds are being distribution randomly in the search area by normal distribution with mean the equal to zero and a variance parameter decreasing over the number of iteration.

In the MEM context, on the other hand, the test of association is based on a variance parameter of the latent gene effects.

The molecular clock assumption was relaxed using uncorrelated rates, with the rate in each branch independently drawn from a log-normal distribution with a mean of 0.01 and a variance parameter of 0.5.

Based on assumption 2, we expect most λ ij ≈ 0. A normal distribution with a fixed variance parameter is not sufficient to impose this constraint.

For a between-trial variance parameter, an example of a non-informative prior could be a gamma distribution with shape and scale parameters of both 10-10.

The BLUP method is usually practiced using a single variance parameter to model the variation of all genes.

Note that the random effect modelling between-study variation is described by a free variance parameter, τ.

As all of the allele frequency trajectories were quite regular, we set σ1 = σ2 in order to have a single variance parameter for the system describing the variation in allele frequency introduced in a 24-hr period.
