Sentence examples for bias in the frequency from inspiring English sources

The potential for recall bias in the frequency of physical activity, sedentary behaviors and dietary habits cannot be completely excluded.

Although a necessary step in the analysis, PCR introduces a bias in the frequency of starting DNA material [ 40- 45].

One interpretation is that this reflects an intrinsic bias in the frequency with which different VDJ H combinations are formed or expressed.

Likewise, genetic analysis of a population of juvenile sea bass showed a highly significant bias in the frequency of lower-jaw protrusion across different full-sib families raised under communal rearing conditions (L. Bargelloni, unpublished data).

Only marginal differences were observed between the dinuICCS and trinuICCS data sets, indicating that the intergenic trinucleotide bias is predominantly caused by bias in the frequency of the underlying dinucleotides.

One is the computational cost necessary for clustering similar oligomers, and the other is the bias in the frequency of fixed-length oligomers, which complicates the detection of significant words.

Here we used the Hershberg and Petrov approach to determine the effect of background composition on the codon bias of 21 plant species while also accounting for bias in the frequencies of dinucleotides and trinucleotides.

The natural statistics of action, that is, biases in the frequency of certain limb positions [42], [43] or spatial biases in muscle spindle firing rates [38], [39], [40], [41] may also play a role in determining differences in proprioceptive function over the workspace.

Many asymmetries in rates would yield biases in the frequency of the two character states observed in the contemporaneous species at the tips of the tree, with stronger asymmetries yielding strong biases.

To estimate biases in the frequency of promoter hexamer sequences, the number of all (4 = 4096) hexamer sequences was determined for 10 000 independent promoters (−1 to −1,000) of Arabidopsis, rice, and soybean.

However, in order to avoid bias in assessing the frequency of MF symptoms, patients who died during the target minimum period of follow-up were included in the study.
