Performs the Anderson-Darling test of goodness-of-fit to a specified continuous univariate probability distribution.
AndersonDarlingTest(x, null = "punif", ..., nullname)numeric vector of data values.
a function, or a character string giving the name of a function, to compute the cumulative distribution function for the null distribution.
additional arguments for the cumulative distribution function.
optional character string describing the null distribution.
The default is "uniform distribution".
An object of class "htest" representing the result of
the hypothesis test.
This command performs the Anderson-Darling test
of goodness-of-fit to the distribution specified by the argument
null. It is assumed that the values in x are
independent and identically distributed random values, with some
cumulative distribution function \(F\).
The null hypothesis is that \(F\) is the function
specified by the argument null, while the alternative
hypothesis is that \(F\) is some other function.
