Nematrian web functions
Functions relating to the above distribution may be accessed
via the Nematrian
web function library by using a DistributionName of “lognormal”.
Functions relating to a generalised version of this distribution including
additional location (i.e. shift) and scale parameters may be accessed by using
a DistributionName of “lognormal4” ”, see also including
additional shift and scale parameters. For details of other supported
probability distributions see here.
