Examples

# chi-squared test statistic for test of independence # of college completion status depending and one's # self-identified income class chisq_stat(gss, college ~ finrela)
#> X-squared #> 30.68252
# chi-squared test statistic for a goodness of fit # test on whether self-identified income class # follows a uniform distribution chisq_stat(gss, response = finrela, p = c("far below average" = 1/6, "below average" = 1/6, "average" = 1/6, "above average" = 1/6, "far above average" = 1/6, "DK" = 1/6))
#> X-squared #> 487.984
