Sentence examples for uses a permutation test from inspiring English sources
One new computer program for spectral analysis improves the standard Lomb Scargle periodogram approach in two ways: (1) It explicitly adjusts the statistical significance to any bias introduced by variance reduction smoothing, and (2) it uses a permutation test to evaluate confidence levels, which is better suited than parametric methods when neighbouring frequencies are highly correlated.
The LA method uses a permutation test for the identification of significant LA gene pair values.
Picante uses a permutation test to test the significance of the observed K value.
This program (PHASE) estimates haplotype frequencies with a Bayesian-based algorithm and then uses a permutation test to determine the significance of differences in inferred haplotypes between cases and controls.
We apply the PERMANOVA procedure (McArdle, 2001) [Permutational Multivariate Analysis of Variance Using Distance Matrices, 'adonis' function from R package 'vegan' (Oksanen et al., 2011)], which partitions the distance matrix among sources of variation, fits linear models to distance matrices and uses a permutation test with pseudo- F ratios to obtain the P-values.
To test the significance of this plot, we used a permutation test (permuting the designation of an "exercise related gene") and as summary test statistic the average squared log2 ratios (the average Euclidean distance from the log2(1)).
We also used a permutation test to further validate the results obtained by the t-tests.
The newly identified genes were further filtered using a permutation test.
Empirical values for chromosome-wise significance thresholds were determined using a permutation test.
We evaluated the level of statistical significance using a permutation test with 1000 iterations, randomly selected subjects and randomly shuffled order of the semantic coordinates across the target objects.
It should be noted that the same significant differences between ipsi- and contraversive trials were seen even after we compared the contra- versus ipsiversive conditions using a permutation test as described in the Methods section.
