getParmsLognormForMedianAndUpper

geometric mu (median at the original exponential scale)

median

value at the upper quantile, i.e. practical maximum

quant

sigmaFac=2 is 95% sigmaFac=2.6 is 99% interval

sigmaFac

Calculates mu and sigma of lognormal from median and upper quantile.

The lognormal distribution
(Limpert et al. (2001) <doi:10.1641/0006-3568(2001)051%5B0341:lndats%5D2.0.co;2>)
can characterize uncertainty that is bounded by zero.
This package provides estimation of distribution parameters, computation of
moments and other basic statistics, and an approximation of the distribution
of the sum of several correlated lognormally distributed variables
(Lo 2013 <doi:10.12988/ams.2013.39511>).
