Description

A list of entities with relative frequencies of appearance.

Synopsis

toFreq :: Text -> [(Int, a)] -> Frequency a
scaleFreq :: Show a => Int -> Frequency a -> Frequency a
renameFreq :: Text -> Frequency a -> Frequency a
setFreq :: Eq a => Frequency a -> a -> Int -> Frequency a
nullFreq :: Frequency a -> Bool
runFrequency :: Frequency a -> [(Int, a)]
nameFrequency :: Frequency a -> Text
minFreq :: Ord a => Frequency a -> Maybe a
maxFreq :: Ord a => Frequency a -> Maybe a
mostFreq :: Frequency a -> Maybe a

The `Frequency` type

data Frequency a Source #

The frequency distribution type. Not normalized (operations may or may not group the same elements and sum their frequencies). However, elements with zero frequency are removed upon construction.

The Eq instance compares raw representations, not relative, normalized frequencies, so operations don't need to preserve the expected equalities.
