kappa distribution - "L-Moments invalid" #14

Closed leannaking closed 1 year ago

leannaking commented 1 year ago

I've imported an AMS of precipitation data and used distr.kap.fit(data). This returns "L-Moments invalid". I am able to calculate L-moments for other distributions including GNO, GLO, GEV, etc.

Why is the kappa distribution not working for this dataset?

I reproduced in R and got the same issue - this time with an error message that Tau3 and Tau4 are above generalized logistic line, so am closing.
