IGTProjection-class: Class IGTProjection

In EHRtemporalVariability: Delineating Temporal Dataset Shifts in Electronic Health Records

Description

Class IGTProjection object contains the estimated Information Geometric Temporal plot projection of a DataTemporalMap object.

Details

Objects of this class are generated automatically by the estimateIGTProjection function, and can be passed to the plotIGTProjection function for plotting the Information Geometric Temporal plot.

Value

A IGTProjection object.

Slots

dataTemporalMap

the DataTemporalMap object from which the projection was estimated

projection

d-by-c matrix of the IGT projection for d temporal batches in c dimensions calculated from the estimateIGTProjection function

embeddingType

embedding function used for the IGT projection calculation in the estimateIGTProjection function

stress

stress achieved in the lower-dimensional embedding, depending on the embedding type (e.g., classicalmds will return 1-GOF as returned by stats::cmdscale function, and nonmetricmds will return final stress in percent, as returned by the MASS::isoMDS function)
