Calculates mu and sigma of the lognormal distribution from median and upper quantile.
1 | twCoefLnorm(median, quant, sigmaFac = qnorm(0.99))
|
median |
geometric mu (median at the original exponential scale) |
quant |
value at the upper quantile, i.e. practical maximum |
sigmaFac |
sigmaFac=2 is 95% sigmaFac=2.6 is 99% interval |
named numeric vector: mu and sigma parameter of the lognormal distribution.
