Chi-square test for discrete 2D data

Description

  pnull,
  dnull,
  phat = function(x) -99,
  minexpcount = 5,
  SuppressMessages = FALSE
)

Arguments

dta	a matrix of numbers.
pnull	distribution function to calculate expected counts.
dnull	density to calculate expected counts.
phat	=function(x) -99, function to estimate parameters of pnull.
minexpcount	=5 minimum counts required per bin
SuppressMessages	=TRUE, should info be shown?

Value

a vector with statistic, p value and degree of freedom
