chi.stat function
Description
This function calculates the $M$ statistics value as defined in the reference paper.
Usage
chi.stat(ftab)
Arguments
ftab |
it is a matrix with dimension 2 by |
Details
The M
statistics is defined as:
M=\sum_{l=1}^{K}\left(\frac{(O_{x,l}-E_{x,l})^2}{E_{x,l}}+\frac{(O_{x,l}-E_{x,l})^2}{\left(n_ln_{l+1}-E_{x,l}\right)}\right)+\sum_{l=1}^{K}\left(\frac{(O_{y,l}-E_{y,l})^2}{E_{y,l}}+\frac{(O_{y,l}-E_{y,l})^2}{\left(m_lm_{l+1}-E_{y,l}\right)}\right).
Value
chi.val, a chisuqre type of statistics value
