Graphical examination of count data may be aided by the use of data transformations chosen to have the property of stabilising the sample variance. In particular, the square root transformation might be used when data can be approximated by a Poisson distribution (although other transformation have modestly improved properties), while an inverse sine transformation is available when a binomial ...
These two one-sided range top-k queries return the top-(/) most frequent elements in each of their respective ranges in (/) time. These frequent elements make up the set of candidates for τ {\displaystyle \tau } -majorities in A [ i . . j ] {\displaystyle A[i..j]} in which there are O ( 1 / τ ) {\displaystyle O(1/\tau )} candidates some of ...
