LogNormalMuErrorFactor¶
- class LogNormalMuErrorFactor(*args)¶
LogNormal distribution parameters.
- Parameters:
- mufloat
The mean of the log-normal random variable.
- EFfloat
The error factor,
- gammafloat, optional
Location parameter.

Notes
The parameter is defined as:
with the quantiles of the log-normal and the centered and reduced gaussian quantile.
Examples
Create the parameters of the LogNormal distribution:
>>> import openturns as ot >>> parameters = ot.LogNormalMuErrorFactor(0.63, 1.5, -0.5)
Convert parameters into the native parameters:
>>> print(parameters.evaluate()) [0.63,0.246505,-0.5]
