DiStatis-class {kimod} | R Documentation

## Class `DiStatis` DiStatis S4 class (kimod: k-tables approach to integrate multiple Omics-Data Multiple dataset)

### Description

Statis with Distance options implementation.

### Features

1. DiStatis (Statis with Distance options)

2. Bootstrap Implementation

3. Biplot Implementation with variable selection

4. Clustering of variables

5. Plotting compromise, bootstrap, trajectories, Biplot.

### Fields

- distances.methods: The character indicating the metrics used.

- Inertia.RV: Inertia (%) explained for all tables.

- RV: Vectorial Correlation Matrix between studies.

- Euclid.Im: Euclidean Image of all studies.

- Inertia.Comp: Inertia (%) explained for all dimensions of compromise matrix.

- Compromise.Coords: Projection of all observations in compromise (Coords).

- Compromise.Matrix: Compromise Matrix from statis methodology.

- RQO: Representation Quality of observations in compromise matrix.

- Trajectories: List of trajectories from Statis methodology
