Generalised logistic distribution growth factors
Estimated growth factors as a function of return period, with inputs of Lcv & LSkew (linear coefficient of variation & linear skewness)
GenLogGF(lcv, lskew, RP)
lcv |
linear coefficient of variation |
lskew |
linear skewness |
RP |
return period |
Growth factors are calculated by the method outlined in the Flood Estimation Handbook, volume 3, 1999.
