ks.test not working?
Hi,
I am performing GEV analysis on temperature/precipitation data and want to use the ks.boot function but I am unsure of how to implement it using the pgev distribution.
For example:
ks.test(data,pgev,shape,location,scale)
ks.boot(data,(distribution parameters?),alternative="pgev",nboots=1000)
Any advice? Apologies in advance if I have used the wrong email address.
Regards,
Louise Wilson

ks.test not working?
Hi,
I am trying the following:
library(ismev)
library(evd)
fit <- gev.fit(x,show=FALSE)
ks.test(x,pgev,fit$mle[1],fit$mle[2],fit$mle[3])
but I am getting:
Warning message:
cannot compute correct p-values with ties in: ks.test(x, pgev,
fit$mle[1], fit$mle[2], fit$mle[3])
where x is:
[1] 239 38 1 43 22 1 5 9 15 6 1 9 156
25 3 100 6

...pply(data, 1:2, function(x) samlmu(x,nmom=4,sort.data=TRUE))
params_GEV <- apply(Lmoments,2:3,pelgev)
location <- params_GEV[1,,] (xi)
scale <- params_GEV[2,,] (alpha)
shape <- params_GEV[3,,] (k)
I want to use the ks.boot function but I am unsure of how to implement it
using the pgev distribution.
For example:
ks.test(data[1,1],pgev,shape[1,1],location[1,1],scale[1,1])
ks.boot(data,(distribution parameters?),alternative=”pgev”,nboots=1000)
Any advice?

Extreme Values - Help with GPD function
...nd the probability that the average weekly U.S. regular gasoline
prices (in the long term) goes over 400 cents a gallon (or $4.00 a
gallon). I am using the extRemes program (in R), and I've already
uploaded my data, and found the probability using the fitted GEV
distribution (I used the pgev function from the evd package). I want
to compare the results from the GEV distribution to those of the GPD
distribution. I've already fitted the GPD distribution to my data (at
a threshold of 400 cents, where there are 52 entries a year (for most
years, at least)) and have obtained the...
