### Cochran-Mantel-Haenzel Test
ct <- cmh_test(y ~ x, data = df)
### chi-squared statistic
statistic(ct)
### the linear statistic, i.e, the contingency table
statistic(ct, type = "linear")
### the same
table(df$x, df$y)
### and the standardized contingency table for illustrating
### departures from the null hypothesis of independence of x and y
