Sentence examples for more constrained model from inspiring English sources

That is, for each studied item, a comparison was made between a full model (all items were allowed to have DIF except for the anchor items) and a more constrained model (all items were allowed to have DIF except for the anchor items and the studied item).

First, the power to detect the effects of interest is much better in the context of a more constrained model.

The baseline measurement model was compared to a more constrained model, including equality of factor loadings over the two assessment points.

Given a significant difference between these models, the more constrained model is rejected and the investigation of measurement invariance does not proceed further.

A non significant Δχ2 (in this study, p >.01) indicates that the more constrained model does not worsen the fit to the data and may be accepted.

A general conclusion is that precise modelling of physiological time series does not markedly increase predictive validity; instead, it appears that a more constrained model and optimised data features provide better results, probably through a suppression of physiological fluctuation that is not caused by the experiment.

More constrained models were compared by subtracting differences in the log-likelihood (−2LL), obtaining a chi-square statistic.

Our implementation, as described in Maddison et al. [ 1] uses several techniques to overcome the limitations of the Brent [ 24] optimizer, including using multiple searches from randomly generated starting points, and the option of starting searches from values estimated from more constrained models.

However, item discrimination and guessing parameters should ideally be evaluated via a full two-parameter logistic model, rather than estimated using the more constrained Rasch model.

No significant difference emerged between both models (ΔSBSχ [ 8] = 8.07, P = 0.43) and, hence, the more parsimonious constrained model was favored, indicating that the final model fitted equally well for boys and girls.

Contrast that with the unhappy video developers who tread too close to the firewall between excessive 3G saturation and the more constrained 3GS upload model, and most developers will overlook the losers and dream of hitting the App Store lottery.
