How to test user-defined distribution using ks.test in R?

[Zhijiang Wang]

Dear All,

I defined a distribution and I want to test it by k-s test?
How to input parameters for ks.test(.....)?
E.g.,
F(x,m) is user-defined function
x is observation value, m is parameter of F

y is observation vector value in experiment

> ks.test(y,"F",m=0.2)
error....


why?

Without the error message? or the function definition? or str(y)?

I would ask "why" you think intelligent commentary should be possible.

Well, R did not say "error", did it?
Where is the definition of F?
What is y?
