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