Fitdistrplus and Custom Probability Density
...y complicated custom probability
distribution to some data.
Fitdistrplus does in principle everything which I need, but if require me
to specify not only the density function d, but also the cumulative p and
and inverse cumulative function q (see for instance
http://www.stat.umn.edu/geyer/old/5101/rlook.html
to understand what these quantities are in the case of a normal
distribution).
The analytical calculation of p and q is a big task in my case, so my
question is if there is a workaround for this, i.e. a way to fit the
unknown parameters of my probability distribution without specifying (at
