Synopsis

# Documentation

type Range a = (a, a) Source #

binBounds :: RealFrac a => a -> a -> Int -> [Range a] Source #

'binBounds a b n' generates bounds for n bins spaced linearly between a and b

Examples:

>>> binBounds 0 3 4
[(0.0,0.75),(0.75,1.5),(1.5,2.25),(2.25,3.0)]


histValues :: RealFrac a => a -> a -> Int -> [a] -> Vector (Range a, Int) Source #

'histValues a b n vs' returns the bins for the histogram of vs on the range from a to b with n bins

histWeightedValues :: RealFrac a => a -> a -> Int -> [(Double, a)] -> Vector (Range a, Double) Source #

'histValues a b n vs' returns the bins for the weighted histogram of vs on the range from a to b with n bins

histWithBins :: (Num w, RealFrac a) => Vector (Range a) -> [(w, a)] -> Vector (Range a, w) Source #

'histWithBins bins xs' is the histogram of weighted values xs with bins

Examples:

>>> :{
histWithBins
(V.fromList [(0.0, 0.75), (0.75, 1.5), (1.5, 2.25), (2.25, 3.0)])
[(1, 0), (1, 0), (1, 1), (1, 2), (1, 2), (1, 2), (1, 3)]
:}
[((0.0,0.75),2),((0.75,1.5),1),((1.5,2.25),3),((2.25,3.0),1)]
