# ops-package: Optimal Power Space Transformation

## Description

Comparison of data by Pearson product-moment correlation coefficients is prone to outliers. The problem can be alleviated by normalizing data with outliers before computing the Pearson correlation coefficient. The sample provides such normalization by optimal power space transformation.

## Details

Use function findP() to compute the exponent for an optimal power space transformation. Optionally, pre-filter the dataset excluding values that are equal or less a certain threshold by calling function filter().
