Sentence examples for prior count from inspiring English sources

Division by zero was avoided by the addition of one prior count to each frequency numerator and denominator before entropy calculation.
Using the edgeR package, counts were normalized by the trimmed mean of M-values method [ 31] and then converted to log2 counts per million with a prior count of 0.25.
