Chi Square Test of Association

Chi Square test of association to examine if there is a relationship between two categorical variables.

infer_chisq_assoc_test(data, x, y)

Arguments

data	a data.frame or tibble
x	factor; column in data
y	factor; column in data

Value

infer_chisq_assoc_test returns an object of class "infer_chisq_assoc_test". An object of class "infer_chisq_assoc_test" is a list containing the following components:

chisquare

chi square

chisquare_lr

likelihood ratio chi square

chisquare_mantel_haenszel

mantel haenszel chi square

chisquare_adjusted

continuity adjusted chi square

contingency_coefficient

contingency coefficient

cramers_v

cramer's v

df

degrees of freedom

ds

product of dimensions of the table of x and y

phi_coefficient

phi coefficient

pval_chisquare

p-value of chi square

pval_chisquare_adjusted

p-value of continuity adjusted chi square

pval_chisquare_lr

p-value of likelihood ratio chi square

pval_chisquare_mantel_haenszel

p-value of mantel haenszel chi square

Deprecated Function
