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 |
getMean()
Returns the mean of the distribution.
|
Double |
getMinValueForProbability(double p)
The value before which the density function will be smaller than p.
|
Double |
getProbabilityAt(double x)
Returns the density function value at a given position.
|
static NonSymmetricalNormalDistribution |
getRobustNonSymmetricalNormalDistribution(ArrayList<Double> input)
Returns the non-symmetrical distribution of the input list of double
calibrated on the median, 15.9% and 84.1% percentiles.

static NonSymmetricalNormalDistribution |
getRobustNonSymmetricalNormalDistributionFromSortedList(ArrayList<Double> input)
Returns the non-symmetrical distribution of the input list of double
calibrated on the median, 15.9% and 84.1% percentiles.
|
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 |
getStdDown()
Returns the standard deviation to the left of the distribution.
|
double |
getStdUp()
Returns the standard deviation to the right of the distribution.
|
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.
