logNormalDistribution
logNormalDistribution(
logMean?,logStandardDeviation?):Distribution
Defined in: log-normal-distribution.ts:20
The log-normal distribution: a variable whose logarithm is normal.
The parameters name the log scale rather than the variable’s own, because
that is what they describe — logMean is not the distribution’s mean, which
is exp(logMean + logStandardDeviation² / 2) and is exposed separately.
Parameters
Section titled “Parameters”logMean?
Section titled “logMean?”number = 0
Mean of the underlying normal.
logStandardDeviation?
Section titled “logStandardDeviation?”number = 1
Standard deviation of it; must be positive.
Returns
Section titled “Returns”The distribution.
Throws
Section titled “Throws”When logStandardDeviation is not positive.
