How to interpret Kolmogorov-Smirnov stats
...imum likelihood
Parameters :
estimate Std. Error
shape1 2.148779 0.1458042
shape2 810.067515 61.8608126
Loglikelihood: 1917.51 AIC: -3831.02 BIC: -3823.15
Correlation matrix:
shape1 shape2
shape1 1.0000000 0.8880194
shape2 0.8880194 1.0000000
now if i do :
>gofstat(fit1, print.test=TRUE)
Kolmogorov-Smirnov statistic: 0.06630064
Kolmogorov-Smirnov test: not rejected
The result of this test may be too conservative as it
assumes that the distribution parameters are known
Cramer-von Mises statistic: 0.3866663
Crame-von Mises test: not calculated

outout clarification of fitdist {fitdistrplus} output
Hello,
I like to fit data against a negative binominal distribution
x2<-c(rep(10,14),rep(9,8),rep(8,13),rep(7,11),rep(6,6),rep(5,18),rep(4,7),re
p(3,21),rep(2,33),rep(1,55),rep(0,225))
f2<-fitdist(x2,"nbinom",method="mle")
plot(f2)
summary(f2)
gofstat(f2)
I receive the following result:
Fitting of the distribution ' nbinom ' by maximum likelihood
Parameters :
estimate Std. Error
size 0.3397148 0.03775577
mu 1.7787630 0.16429774
Loglikelihood: -701.0615 AIC: 1406.123 BIC: 1414.16
------
I am wondering how...

list(prob=1/2,shape1=1,scale1=1,shape2=1,scale2=1),lower=0)
cdfcomp(list(fgam, fpar, fmixgam), xlogscale = TRUE)
