Sentence examples for by analysis of deviance from inspiring English sources

As indicator for the improvement from the null model to the two-level model, we calculated McFadden's (1973) adjusted R-squared (= 1−[−2LL2-level model/−2LLnull model] = 1−[9,827.192−10,039.848]) and found an error reduction of only 2.1percentt, but which remains significant by analysis of deviance (χ2-test).

The statistical significance of main effects and interaction terms in the model was tested with F-tests by analysis of deviance, which involved looking at the change in deviance caused by the removal of each term from the maximal model after having allowed for overdispersion in the data by calculating a variance heterogeneity coefficient with the Williams algorithm (25, 26 ).

Further, the effects of each variable selected in the model and the possible interactions between variables were tested by an analysis of deviance.

Models fit to the data were compared by chi-square analysis of deviance.

Variation in final frequencies of virulent isolates in the field competition experiments were analysed by means of Analysis of Deviance, based on a logistic regression (GENMOD procedure; SAS).

The analysis of deviance penalized by the dispersion parameter [ 17] was used to assess the relevance of the variability.

A reduced model was compared with a non-factor model with only interception using the analysis of deviance test by the procedure "anova".

Each step was followed by tests for significance of variables with higher degree of freedom, an analysis of deviance table, and sensitivity analysis which was done by removing one variable at the time and looking at changes of beta-coefficients.

We can thus construct a likelihood ratio test by comparing the maximised weighted likelihoods of two models via analysis of deviance: (i) the null model where β = 0; and (ii) the alternative model for which β is unconstrained.

When the degrees of freedom for the smoothed term were near their minimum value, we examined whether the trend was described sufficiently by a linear regression using Akaike's information criterion (AIC) and analysis of deviance between the two models.

We experimentally observed differences in susceptibility to both carbaryl and potassium dichromate among the studied pond populations of D. magna (analysis of deviance, P < 0.001).
