The EnvStats functions listed below are useful for performing goodnessoffit tests for userspecified probability distributions.
GoodnessofFit Tests
Function Name  Description 
gofTest  Perform a goodnessoffit test for a specified probability distribution. 
The resulting object is of class "gof" unless the test is the 

twosample KolmogorovSmirnov test, in which case the resulting  
object is of class "gofTwoSample" . 

plot.gof  S3 class method for plotting an object of class "gof" . 
print.gof  S3 class method for printing an object of class "gof" . 
plot.gofTwoSample  S3 class method for plotting an object of class "gofTwoSample" . 
print.gofTwoSample  S3 class method for printing an object of class "gofTwoSample" . 
gofGroupTest  Perform a goodnessoffit test to determine whether data in a set of groups 
appear to all come from the same probability distribution  
(with possibly different parameters for each group).  
The resulting object is of class "gofGroup" . 

plot.gofGroup  S3 class method for plotting an object of class "gofGroup" . 
print.gofGroup  S3 class method for printing an object of class "gofGroup" . 
Tests for Outliers
Function Name  Description 
rosnerTest  Perform Rosner's test for outliers assuming a normal (Gaussian) distribution. 
print.gofOutlier  S3 class method for printing an object of class "gofOutlier" . 
Choose a Distribution
Function Name  Description 
distChoose  Choose best fitting distribution based on goodnessoffit tests. 
print.distChoose  S3 class method for printing an object of class "distChoose" .
