Create a cross-tabulation (contingency table) t from data vectors.
The inputs x1, x2, ... xn must be vectors of equal length with a data type of numeric, logical, char, or string (cell array).
As additional return values crosstab
returns the chi-square statistics
chi-2, its p-value p and a cell array labels, containing
the labels of each input argument.
Currently chi-2 and p are available only for 1 or 2-dimensional
t, with crosstab
returning a NaN value for both chi-2 and
p for 3-dimensional, or more, t.
