# Minimum significant correlation for a sample size

### Description

`minSigCor`

is a helper function that estimates the minimum
significant correlation for a smaple size `n`

at a confidence level
defined by the argument `alpha`

.

### Usage

1 |

### Arguments

`n` |
sample size or the length of a timeseries vector. |

`alpha` |
confidence level: the default is |

`r` |
a vector of values from |

### Details

`minSigCor`

function estimates the minimum significant correlation
for a sample size (number of observations or temporal points in a timeseries)
at a certain confidence level selected by the argument `alpha`

and an
optional search range `r`

. It is called by `validClimR`

function objective tree cut based on the specified confidence level.

### Value

A positive value beween `0`

and `1`

for the estimated the minimum
significant correlation.
