Hi,

I'll cut to the core of the problem that I had.

The answer involves converting two gamma distributions to normal distributions and then adding the two normal distributions using the additive property of the normal distribution.

What i did was to add the two gamma distributions first and then convert to a normal distribution. But this is wrong as the mean and variance are too small.

Can I add to gamma distributions? I know that i can add lots of exponential distributions into one gamma.

Regards
R
