alkanes: Methylalkanes Retention Index Dataset

In road2stat/enpls: Ensemble Partial Least Squares Regression

Description

Methylalkanes retention index dataset from Liang et, al.

Usage

data("alkanes")

Format

A list with 2 components:

• x - data frame with 207 rows (samples) and 21 columns (predictors)

• y - numeric vector of length 207 (response)

Details

This dataset contains 207 methylalkanes' chromatographic retention index (y) which have been modeled by 21 molecular descriptors (x).

Molecular descriptor types:

• Chi path, cluster and path/cluster indices

• Kappa shape indices

• E-state indices

• Molecular electricity distance vector index
