groupMinSize :: Eq a => Int -> a -> [a] -> [[a]]Source

Similar to group, but in case a group is smaller than s, the group is filled with the same number of a's:

>>> groupMinSize 3 0 [1,2,2,3,3,3,4,4,4,4,5,5,5,5,5]
[[0],[0,0],[0,0,0],[4,4,4,4],[5,5,5,5,5]]

listMean :: [NumData] -> NumData Source

Returns the mean of list.

medianFilter :: Ord a => Int -> [a] -> [a]Source

a median filter: see http://en.wikipedia.org/wiki/Median_filter.

getWindows :: Ord a => Int -> [a] -> [[a]]Source

Returns a list with all sliding windows of a particular size. The left and right edge of the list are filled with the first and last (size 2) items, respectively and the remainder is filled with the modemedian of the complete list.

hasSize :: Int -> [a] -> Bool Source

mode :: Ord a => [a] -> aSource

The mode: the element that occurs most often in the collection.

median :: Ord a => [a] -> aSource

Returns the median of a list.

maxListIndex :: Ord a => [a] -> Int Source

Returns the index of th maximal element of a list.
