Cdf(lowBound,upBound,df) ⇒ number if lowBound and
upBound are numbers, list if lowBound and upBound are lists
chi2Cdf(lowBound,upBound,df) ⇒ number if lowBound and
upBound are numbers, list if lowBound and upBound are lists
Computes the c

distribution probability between lowBound and
upBound for the specified degrees of freedom df.
For P(X
{ upBound), set lowBound = 0.
For information on the effect of empty elements in a list, see “Empty

GOF obsList,expList,df
chi2GOF obsList,expList,df
Performs a test to confirm that sample data is from a population that
conforms to a specified distribution. obsList is a list of counts and
must contain integers. A summary of results is stored in the
stat.results variable. (See page 97.)
For information on the effect of empty elements in a list, see “Empty
(void) elements” on page 131.
