ifisherZ {compartmap} | R Documentation

## Fisher's Z transformation

### Description

`fisherZ` returns the inverse (squeezed) Fisher's Z transformed Pearson's r. This will fail if a matrix is used as input instead of a vector.

### Usage

    ifisherZ(cormat)

### Arguments

`cormat` | vector of Fisher's Z transformed Pearson correlations or an eignevector

### Details

This function returns the inverse (squeezed) Fisher's Z transformed Pearson's r

### Value

Back transformed Fisher's Z

### Examples

    #Generate a random binary (-1, 1) matrix
    mat <- matrix(sample(c(1,-1), 10000, replace = TRUE), ncol = 100)

    #Correct matrix diag
    diag(mat) <- 1

    #Transform
    mat.transform <- fisherZ(mat)

    #Back transform
    mat.transform.inverse <- apply(mat.transform, 1, ifisherZ)
