Implementation of the Anderson-Darling goodness of fit test.
Usage
ad.test(x, distr.fun, ...)
Arguments
x
a random sample from a possibly unknown continuous distribution
distr.fun
a named CDF, such as pnorm, punif, etc.
...
extra parameters for the distribution function above, such as location and scale parameters, etc.
Value
The output is an object of the class htest exactly like for the Kolmogorov-Smirnov test, ks.test.
The statistic and p.value fields are the most relevant ones.
Details
If the distr.fun is provided, the function checks whether x is a iid sample from the distribution described by such CDF.
Otherwise, whether they follow a uniform law.
