implementing Maximum Likelihood with distrMod when only the PDF is known
...of some univariate data for which I have derived a theoretical continuous density (pdf). As it is a parametric density, I guess that I should implement myself a new distribution of class AbscontDistributions (as stated in the pdf on "creating new distributions in distr"), and then use MLEstimator() from the distrMod package. Is that correct or is there a simpler way to go? Note that I want to use the distr package because it allows me to implement simply the convolution of my theoretical pdf with some noise distribution that I want to model in the data, this is more difficult with...
