Extract Test Statistics, Linear Statistics and Standardized
Statistics
Description
Extract the test statistic and, possibly multivariate, linear statistics
in their raw and standardized form from objects of class
IndependenceTest-class
.
Usage
statistic(object, type = c("test", "linear", "standardized"), ...)
Arguments
object |
an object inheriting from class
IndependenceTest-class . |
type |
either test for test statistic, linear
for the unstandardized linear statistic or standardized
for the standardized linear statistic. |
... |
further arguments (currently ignored). |
Methods
- statistic
- extracts the specified statistic from
object
.
Examples
df <- data.frame(y = gl(4, 5), x = gl(5, 4))
### 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
statistic(ct, type = "standardized")
