# k-Sample version of the Fligner-Kileen test for homogeneous scales.

### Description

Returns the Fligner-Kileen test for homogeneous scales for k-samples. Also estimates of ratio of scales based on the logs of folded median-aligned samples and a corresponding confidence interval is computed. The first level (sample) is referenced. See the discussion in Section 5.7 of Kloke and McKean (2014).

### Usage

1 | ```
fkk.test(y,ind,conf.level = 0.95)
``` |

### Arguments

`y` |
vector of responses |

`ind` |
vector of corresponding levels |

`conf.level` |
confidence coefficient for the returned confidence intervals |

### Details

Returns the Fligner-Kileen test for the k-sample scale problem.

### Value

`statistic` |
chi-squared test statistic |

`p.value` |
p-value of the test |

`estimate` |
vector of estimates of ratio of scales |

`conf.int` |
table of confidence intervals |

`cwts` |
vector of weights based on the estimates difference in scales |
