Double |
getCumulativeProbabilityAt(double x)
Returns the cumulative density function value at a given position.
|
Double |
getDescendingCumulativeProbabilityAt(double x)
Returns the cumulative density function value at a given position when
starting from the high values.
|
Double |
getMaxValueForProbability(double p)
The value after which the density function will be smaller than p.
|
Double |
getMinValueForProbability(double p)
The value before which the density function will be smaller than p.

static NormalDistribution |
getNormalDistribution(ArrayList<Double> input)
Returns the normal distribution corresponding to a given list of double
calibrated on mean and standard deviation.
|
Double |
getProbabilityAt(double x)
Returns the density function value at a given position.
|
static NormalDistribution |
getRobustNormalDistribution(ArrayList<Double> input)
Returns the normal distribution corresponding to a given list of double
calibrated on median and 34.1% percentile to median distance
|
Double |
getSmallestCumulativeProbabilityAt(double x)
Returns the cumulative density function value at a given position, starting from the low values if before the median, from the high otherwise.
|
Double |
getValueAtCumulativeProbability(double p)
The value after which the cumulative density function will be smaller
than p.
|
Double |
getValueAtDescendingCumulativeProbability(double p)
The value after which the cumulative density function will be smaller
than p when starting from high values.
