extracting a and b beta parameters from distribution fitter app

so I used the distribution fitter app to find the best PDF for my data and i found the best fit to be the beta pdf. i then saved the pdf parameter to my workspace.

and when i exctract the parameters they come in this form:

Beta distribution

a = 0.488112 [0.385556, 0.617948]

b = 1.3023 [0.817649, 2.07421]

how can i only exctract a and b.

If your save object is mybetaObject then

myBetaObject.ParameterValues  % both a, b

or

myBetaObject.a                
myBetaObject.b

for each. Hard to glean from the doc if use the app; see the description of the fitted distribution objects throuth the fitdist doc link for each distribution.

OBTW...use tab completion at the command line after the object variable name to see the list of properties, procedures.
