[R] Fitting gamma and exponential Distributions with fitdist

[vioravis]

Joshua, thanks for your reply.

I have tried out the following scaling and it seems to work fine:

scaledVariable <- (test-min(test)+0.001)/(max(test)-min(test)+0.002)  

The gamma distribution parameters are obtained using the scaled variable and
samples obtained from this distributions are scaled back using:

scaled <- (randomSamples*(max(test) - min(test) + 0.002)) + min(test) -
0.001

Is there a better way to scale the variable???  I would prefer fitting a
distribution without scaling it.

Thank you.

Ravi
