weightedVar: Calculation of Outlier-Robust Weighted Variance

In nishithkumarpaul/Rvolcano: Robust Volcano Plot: Identification of Influential Metabolites in the Presence of Outliers

Description

This function calculates the outlier-robust weighted variance in presence of outliers. A kernel weight function has been used behind this function.

Usage

weightedVar(x, b)

Arguments

x	a numerical vector of metabolomic measurements.
b	value of tuning parameter. Default value is 0.25.

Value

Computed the weighted variance.
