I'm using Craig Markwardt's fitting routine MPFITFUN.PRO. I use an
expression called the Dorman function, to fit the given data points.
I don't get a proper fit, doesn't matter which starting params I use.
This is my code:

function dorman, x,p
return,P(0)*P(1)*148.1*(X^(-P(1)-1.0))*exp(-P(0)*X^(-P(1)))
end

start=[1.5D, -0.5]
p=MPFITFUN('dorman',x,y,rerr,start)
yy=dorman(x,p)

oplot, exp(x), exp(yy), color = 150 ; using natural log axes.

What am I doing wrong?
Thanks for any help.
