min_max_GM {Indicator}

Normalization for the Geometric Mean

Description

This is a data normalization function for the geometric mean, where we multiplied the normalized data by 198 and add 1, with positive or negative polarity

Usage

min_max_GM(data, pol = "pos")

Arguments

data

dataframe with rows = observations and columns = quantiative

pol

polarity if not selected is "positive"", otherwise write "neg"

Details

The ‘polarity’ of an indicator is the sign of the relation between the indicator and the phenomenon to be measured ( + if the indicator represents a dimension considered positive and - otherwise)

Value

It returns a datafame of normalized data
