Sentence examples for sample the null from inspiring English sources

The mean maps were summated to a joint likelihood map and 10,000 permutations used to sample the null distribution and test the probability that any given voxel of the joint likelihood map was significant.

Because it is based on the relative enrichment, this test did not deal well with background noise and led to a high false positive rate: when in a given region, few random reads (a couple) were present in the nucleosome sample but not in the control sample, the null hypothesis (equal enrichment in both samples) was rejected and the region declared as nucleosome.

Probabilistic thresholding was performed in two-stages: First at the voxel-level, all values at all intracerebral voxels from the permuted response maps were pooled to sample the null-distribution.

The null distributions of statistic under the competitive hypothesis are generated by gene sampling; the null distributions under the self-contained hypothesis are generated by subject-sampling.

Nestedness analyses were run using the nestedness function as implemented in the R library Bipartite57 and the null model 3 as suggested by Rodríguez‐Gironés and Santamaría64, which is a constrained null model that accounts for the frequency of genera (column totals) and the genus richness of fossil sites (row totals) while sampling the null space uniformly, which minimises type I and II errors.

The identification of metabolic fluxes obeying the steady-state condition,

The paper describes a novel and efficient method for sampling the null distributions that calibrate the significance of nestedness scores.

For these samples, the null hypothesis μ X =  μ Y was tested against the alternative μ X ≠  μ Y using Student's  t test at the two-sided significance level α  = .05.05

Since the permutation samples are pooled across all replicates to form a sample from the null, B can be set to be much smaller than the situation when only one sample is analyzed.

When the sample index δ is placed at the first sample of the null symbol, the energy ratio P δ would have a maximum value.

Therefore, we propose the following steps to reduce the computational burden by pooling permutation samples from all replicates to form a joint sample from the null distribution.
