Simple programs to perform chi-squared tests:

• chisq - chi-squared calculation
• chisig - calculate the significance for a given chi-squared value and degrees of freedom
• chitab - calculate critical chi-squared value for a given significance and degrees of freedom
• chisq3 - 3-way chi-squared calculation
• cellsignificance.pl - calculate significance for a single cell
• csv2chi.pl - rewrite a CSV file with table and column headers in the required format
• csvh2chi.pl - rewrite a CSV file with column headers only in the required format
• tabulate.pl - writes a table of chi-squared values for different levels of significance and degrees of freedom
• twobytwo.pl - Creates a 2x2 contingency table from a larger table

Compile this with:

   make

Note it doesn't really need g++ except that the library routines use C++ style comments and therefore need to be compiled with g++. To get the linker to work properly, this then has to be compiled with g++ as well!
