So, an underestimation of 0.25 of the variance of the latent variable in this example leads to a decrease of 13.8% of the power of the test of group effect.
The variance σ, for each of four payoff outcomes may vary independently as σT, σR, σP, σS (where σT is the variance of T, for example).
For example, the variance of the trend goes from 4.7 to 5, whereas the variance of the cyclical component goes from 1.07 to 1.25.
In addition, where this methodological variance does exist, then, according to generalizability theory (Brennan 2001) it should be added to the actual variance of the coefficients across countries (by, for example, increasing the standard errors of the coefficients).
For example, the variance of the sequence similarity score in " i" is large, which might arise because of different specificity, horizontal gene transfer, gene fusions, or the fact that only subunits of the enzymes are the same.
When we are interested in the extent to which individual differences on the latent trait are heritable, we only need to decompose the variance of the θ j s using, for example, the classical twin design.
The analysis was focused on these three pig chromosomes because previous detection analyses [ 6- 12] have shown that the QTL identified on these chromosomes contribute less to the global variance of the traits than QTL detected for example on SSC7 or SSCX.
The variance-fold is defined as the quotient of the variance of one group (for example, OA patients) and the variance of another group (for example, RA patients).
This allows us to derive a relationship between adversity and subjective resource uncertainty (i.e., the variance of the resource distribution after ignoring the resources below the minimum acceptable cut-off point – for example the variance of the distribution of sizes of acceptable food items, which are sufficiently big to be above the minimum acceptable cut-off point).
varvar sets the variance of the gaussians.
In the first case (Marginal Maximum Likelihood estimation, MML, cf. Baker and Kim 2004, ch. 6), the incidental parameters θ v are replaced by assuming a proper distribution G in the population (e.g. the normal), requiring only the hyperparameters τ of G to be determined (i.e. the mean and the variance of G in our example).
