Hi peter,

Quite an insight you have there hehe. i am continuing on from the orignal problem of creating a simulation.

Im now trying to find (n−1)S2/σ2, and fit it to a chi squared dist with 5 degrees of freedom.
 
im having trouble with the coding for this. i think for the second part of that i need to use the fitdist function, but to get it to where i am able to do that, im not sure what to do.
 
THis is what i have been trying to do so far, but it hasn't returned me anything good
sum((x-mean(x))^2)/(length(x)-1)
i am really confused, can someone please help?
 
Cheers
