stat_early_conservation_test: Early Conservation Test

Description

Test for early conservation patterns in transcriptomic data by comparing early developmental stages to mid and late stages.

Usage

stat_early_conservation_test(phyex_set, modules, ...)

Value

A ConservationTestResult object with early conservation test results

Arguments

phyex_set

A PhyloExpressionSet object

modules

A named list with elements 'early', 'mid', and 'late' containing stage indices for each developmental module

...

Additional arguments passed to stat_generic_conservation_test

Details

The early conservation test evaluates whether early developmental stages show lower transcriptomic index values (indicating older genes) compared to later stages. The test computes a score based on the minimum difference between mid vs. early and late vs. early TXI values.

Examples

# Define developmental modules
p <- example_phyex_set_old |> 
     select_genes(example_phyex_set_old@gene_ids[1:100])
modules <- list(early = 1:2, mid = 3:5, late = 6:7)
result <- stat_early_conservation_test(p, modules=modules)
