flopscope.stats.lognorm
flopscope.stats.lognorm
Log-normal continuous random variable.
This object mirrors scipy.stats.lognorm.
Notes
s is the shape parameter: the standard deviation of the underlying
normal distribution. It is the first positional argument, ahead of
loc and scale, matching SciPy's lognorm signature. pdf
