R help - May 2017 - Non-standard Beta distribution

Hi,

I would like to fit a non standard beta distribution with the two scale
parameters and lower and upper boundaries to data like  the one shown
without normalizing it.

[1] 37.50 46.79 48.30 46.04 43.40 39.25 38.49 49.51 40.38 36.98
40.00[12] 38.49 37.74 47.92 44.53 44.91 44.91 40.00 41.51 47.92 36.98
43.40[23] 42.26 41.89 38.87 43.02 39.25 40.38 42.64 36.98 44.15 44.91
43.40[34] 49.81 38.87 40.00 52.45 53.13 47.92 52.45 44.91 29.54 27.13
35.60


I have tried using the following code;

fitdist((Z1-r)/(t-r) , "beta", method = "mme",lower=c(0,0))

but with this I am normalizing the data to be in the interval (0,1) .


Thanks.

You could try installing package ExtDist and using distribution Beta_ab in that
package.
