Hello everyone,
I am using fgev from evd package to fitting my data with general extreme
value distribution. The command I used is simple: y <- fgev(x).
The error is "observed information matrix is singular;" How can I solve
these problem. I tried all methods in optim and it did not work. I fixed
values for scale, location and shape. This works, but I have lots of
different dataset to fit, so is there any automatic ways to solve the
error? Thanks!
jinrui,
