In LCA: Localised Co-Dependency Analysis

Description Usage Arguments Details Value Author(s)

Use PTL model to estimate the significance of a difference between the values of some feature of interest in two selected objects from a dataset.

1	evaluateDiffSignificance(d,diff,PTLmodel)

`d`	Numeric value specifying global dissimilarity between the selected objects
`diff`	Numeric value specifying magnitude of difference between the values of a selected feature of interest in the selected objects
`PTLmodel`	List, as returned by the function `fitPTLmodel`, with named elements `alpha`, `beta` and `gamma` specifying linear models for PTL parameter prediction.

Evaluates statistical significance of observing as great a difference as that observed between the values of a selected feature of interest in the selected objects, given the global dissimilarity between those objects and the PTL models fitted to characterise these distributions across the whole dataset.

Numeric value giving p-value representing significance estimate of the observed difference, given the fitted models.
