##### Cramer-Von Mises Test of Goodness-of-Fit

Performs the latex{Cram'er}{Cramer}-von Mises test of goodness-of-fit to a specified continuous univariate probability distribution.

Keywords
htest
##### Usage
cvm.test(x, null = "punif", ..., nullname)
##### Arguments
x
Numeric vector of data values.
null
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.
nullname
Optional character string describing the null distribution. The default is "uniform distribution".
##### Details

This command performs the latex{Cram'er}{Cramer}-von Mises 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.

##### Value

• An object of class "htest" representing the result of the hypothesis test.
