I am trying to fit a skew normal distribution to some data. I only have data from the left tail. My code is as follow: using Optim using Distributions using QuadGK unction T(h, a) return 1/(2*π) * quadgk(x -> exp(-(1/2) * h^2 * (1+x^2)) / (1 + x^2), 0 , a)[1] end function skewnormalcdf(args, x…

Instead of giving your problem more exposure (as you may expect), it just scatters solutions all over the place.
