Sentence examples for prediction of sample size from inspiring English sources

Prediction of sample size in cluster randomised trials is difficult given the fact that not only the expected effect size has to be estimated, but also the anticipated cluster size and intra-cluster correlation coefficient[ 43].

Data from these calibration experiments are sufficient to make estimates of statistical power and predictions of sample size and minimum observable effect sizes.

Some categories were producing consistently better predictions, regardless of sample size (2, 4, 9 and 10).

For the derivation of prediction models, standard calculations of sample size do not apply since these calculations do not account for the model development process (ie, selection of variables and the optimisation to achieve specified sensitivity and specificity cut-offs).

The effects of sample size on prediction accuracy are clear.

Different validation (V) procedures were used to evaluate the effect of different factors on genomic prediction for hybrid performance: (V1) Effect of sample size and number of test environments: Fivefold cross validation was conducted by subdividing the 255 hybrids of Experiment 1 randomly into five disjoint subsets.

Fassnacht, F. et al. Importance of sample size, data type and prediction method for remote sensing-based estimations of aboveground forest biomass.

An empirical method of sample size determination for building prediction models was proposed recently.

Although our example of using eye color to monitor the effect of sample size to the AUC-based prediction accuracy of pigmentation traits indicate that the sample size used here for hair color prediction is large enough to obtain a reasonably accurate prediction model, our results may be further replicated in a larger study.

Further studies are needed to better understand the factors contributing to these differences, such as sensitivities of the assays, use of very short DNA fragments in MPRAs, methods of ascertaining the predictions, and effects of sample sizes.

Predictions of power, sample size and minimum observable effect size (difference in group means) are available across a range of common study designs.
