Example sentences for: positives

How can you use “positives” in a sentence? Here are some example sentences to help you improve your vocabulary:

  • A PSI-BLAST search was initiated with the conserved N-terminal extension of the SGC (human SGC1β, gi: 4504215, region 1-360), using an inclusion threshold of .01, and compositional bias based statistics to eliminate false positives arising due to peculiarities of sequence composition.

  • The tradeoff can be chosen by an investigator based upon the relative cost of false positives and value of detecting differences in genes expressed at low levels.

  • We now show that fold-difference alone results in a high degree of error whilst detecting regulated genes from microarrays, replicate arrays with statistical analysis reduces false positives and negatives.

  • This property was exploited to estimate and correct for the level of hybridization contributed by non-specific binding, enabling the selection of optimal oligodeoxyribonucleotides and the reduction of false positives in exon identification.

  • Similarly, we define the false-negative rate ( FN ) as the number of false negatives among the nonsignificant genes divided by the total number of genes, the true-positive rate ( TP ) as the number of true positives divided by the total number of genes, and, the true-negative rate ( TN ) as the number of true negatives divided by the total number of genes.
