README - Stdresid for TI-89
---------------------------

Summary:
   The stdresid program calculates standardized residuals for chi-square 
   tests based on observed and expected counts.

Instructions:
   1) Enter observed counts into a matrix using the data/matrix editor
   2) Enter expected counts into a matrix in one of two ways
      a) Manually enter data using the data/matrix editor
      b) Run a chi-square 2-way test using the stats/list editor, which will
         store the expected values in the statvars\expmat matrix
   3) Switch to home and type in stdresid(obs, exp), where obs is the name of
      matrix containing the observed counts and exp is the name of the matrix 
      containing the expected counts. Entering the VAR-LINK dialog will allow
      you to choose matrices from a list of data (2nd -> -).
   4) The resulting standardized residuals matrix will both be displayed on 
      the screen and stored in statvars\stdresid
