I have the parameters of a gamma distribution that I am trying to plot. The
parameters are shape = 2, scale = 5.390275 and the minimum value x0 is
65.44945.
Since the gamma is shifted by x0, we have
Mean = shape*scale + x0 = 76.23
My question is, how can I do it in r?
I was trying to use dgamma function, but I saw no options to offset the
gamma distribution. I can only use the shape and scale parameters, like
this:
> x <- seq(from=0, to=100, length.out=100)
> plot(x, dgamma(x, shape=2, scale=5.390275),
main="Gamma",type='l')
This generates a distribution with origin equal zero, but I want the origin
to be x0
How can I handle shifted gamma distribution in r?
Thanks a lot!
Rodrigo.
