Chacko_test_1xc {contingencytables} | R Documentation |

## The Chacko test for order-restriction

### Description

Described in Chapter 3, "The 1xc Table and the Multinomial
Distribution", Chacko (1966) derived a test based on the Pearson chi-square
statistic to test the hypothesis that the categories of a multinomial
variable with `c`

possible outcomes have a natural ordering. The test
statistic is asymptotically chi-squared distributed.

### Usage

```
Chacko_test_1xc(n)
```

### Arguments

`n` |
the observed counts (a 1xc vector, where c is the number of categories) |

### Value

An object of the contingencytables_result class,
basically a subclass of `base::list()`

. Use the `utils::str()`

function
to see the specific elements returned.
