CT_Coefficient {ConcordanceTest} R Documentation

## Concordance Coefficient and Kruskal-Wallis Statistic

### Description

This function computes the Concordance coefficient and the Kruskal-Wallis statistic.

### Usage

```CT_Coefficient(Sample_List, H = 0)
```

### Arguments

 `Sample_List` List of numeric data vectors with the elements of each sample. `H` 0 by default. If set to 1, the Kruskal-Wallis statistic is also calculated and returned.

### Value

The function returns a list with the following elements:

1. `Sample_Sizes`: Numeric vector of sample sizes.

2. `order_elements`: Numeric vector containing the elements order.

3. `disorder`: Disorder of the permutation given by `order_elements`.

4. `Concordance_Coefficient`: 1-relative disorder of permutation given by `order_elements`.

5. `H_Statistic`: Kruskal-Wallis statistic (only if H = 1).

### Examples

```## Example
A <- c(12,13,15,20,23,28,30,32,40,48)
B <- c(29,31,49,52,54)
C <- c(24,26,44)
Sample_List <- list(A, B, C)
CT_Coefficient(Sample_List)
CT_Coefficient(Sample_List, H = 1)

## Example with ties
A <- c(12,13,15,20,24,29,30,32,40,49)
B <- c(29,31,49,52,54)
C <- c(24,26,44)
Sample_List <- list(A, B, C)
CT_Coefficient(Sample_List, H = 1)
```
