when expected cell frequences are less than 5.
1 | chi.squared.test(x, y = NULL, conservative = FALSE, cramers.v.conf = 0.95, simulate.p.value = FALSE, B = 10000)
|
x |
A vector or a matrix |
y |
A vector that is ignored if x is a matrix and required if x is a vector |
conservative |
If FALSE, the usual chi-squared test is performed and if simulate.p.value=TRUE, the monte carlo mid p-value is returned. Otherwise, Yates' continuity correction is applied, and if simulate.p.value=TRUE the monte carlo conservative p-value is returned |
cramers.v.conf |
The confidence level for the confidence interval around the Cramer's V effect size |
simulate.p.value |
a logical indicating whether to compute p-values by monte carlo simulation |
B |
An integer specifying the number of replicates used in the monte carlo test |
A list with class “htest” containing the following components:
statistic |
the value the chi-squared test statistic. |
parameter |
the degrees of freedom of the approximate chi-squared distribution of the test statistic. |
p.value |
the p-value for the test. |
method |
a character string indicating the type of test performed, and whether Monte Carlo simulation or continuity correction was used. |
data.name |
a character string giving the name(s) of the data. |
observed |
the observed counts. |
expected |
the expected counts under the null hypothesis. |
residuals |
the Pearson residuals, (observed - expected) / sqrt(expected). |
estimate |
Cramer's V |
conf.int |
A confidence interval for Cramer's V |
