gamfit
Fit a gamma distribution to a data sample.
Syntax
[ahat,bhat,aci,bci]=gamfit(x)
Inputs
- x
 - Data sample.
 
Outputs
- ahat
 - An estimate of the shape parameter a.
 - bhat
 - An estimate of the scale parameter b.
 - aci
 - A confidence interval for a. A two-element vector containing the lower and upper bounds of the interval.
 - bci
 - A confidence interval for b. A two-element vector containing the lower and upper bounds of the interval.
 
Example
x = [9 12.88 6.56 12.4 1.72 14.38 9.55 8.48 3.76 11.6 6.7 29.14 9.76 13.2 19.95 11.77
 8.47 7.23 7.36 7.24]
[ahat,bhat,aci,bci] = gamfit(x)
      ahat = 3.5765
bhat = 2.9519
aci = [Matrix] 2 x 1

bci = [Matrix] 2 x 1
