Granite.Stat

Description

Statistical transforms (Stat). Each runs on a layer's mapped X / Y columns and returns a new frame, generally with the same column names holding the transformed values. StatBoxplot additionally writes __ymin __q1 __median __q3 __ymax for the boxplot geom to read.

Synopsis

applyStat :: Stat -> Mapping -> DataFrame -> DataFrame
binData :: BinSpec -> [Double] -> ([Double], [Double])
kdeData :: Int -> [Double] -> ([Double], [Double])
smoothLm :: [Double] -> [Double] -> [Double]
smoothMovingAvg :: Int -> [Double] -> [Double]
smoothLoess :: Double -> [Double] -> [Double] -> [Double]
boxplotSummary :: [Double] -> BoxStats
data BoxStats = BoxStats {
- yMin :: !Double
- q1 :: !Double
- med :: !Double
- q3 :: !Double
- yMax :: !Double
}
countByCategory :: [Text] -> [(Text, Int)]
summarizeByCategory :: SummaryFun -> [(Text, Double)] -> [(Text, Double)]

Documentation

applyStat :: Stat -> Mapping -> DataFrame -> DataFrame Source #

binData :: BinSpec -> [Double] -> ([Double], [Double]) Source #

kdeData :: Int -> [Double] -> ([Double], [Double]) Source #

Gaussian KDE on n grid points; bandwidth is Silverman's rule.

smoothLm :: [Double] -> [Double] -> [Double] Source #

OLS regression, evaluated at the input X positions.

smoothMovingAvg :: Int -> [Double] -> [Double] Source #

Trailing moving average; leading edge is the partial-window mean so the output length matches the input.

smoothLoess :: Double -> [Double] -> [Double] -> [Double] Source #

LOESS-style local linear regression with tricube weights; span_ is the neighbourhood fraction in (0, 1].

boxplotSummary :: [Double] -> BoxStats Source #

Five-number summary using Tukey hinges: when n is odd the median is included in both halves, so boxplotSummary [1..9] gives (1, 3, 5, 7, 9).
