Quantlet: | crosstable | |
Description: | computes pairwise crosstables from all columns of a data matrix, gives the result of a Chi-square independence test and computes contingency coefficients. |
Usage: | cross=crosstable(x{,xvars}) | |
Input: | ||
x | n x p matrix, the columns correspond to the variables. | |
xvars | optional, p x 1 string vector, variable names. | |
Output: | ||
cross | string output, containing all crosstables of each combinations of columns of x, the result of the Chi-square independence tests and contingency coefficients. |
library("stats") randomize(970701) x = ceil(normal(100,2)) ; rounded independent random numbers crosstable(x)
the crosstable of the columns of x. The significance level of the Chi-square independence test should NOT indicate rejection.
