Perform T-Test on Pseudo-Cell Delta Values

pseudo_cell_t_test.Rd

This function reconstructs a phylogenetic tree for a specific chromosome and allele, then performs a one-sample t-test on the delta values (difference between G and B distances).

Usage

pseudo_cell_t_test(fit, chr, allele, mu = 0, sign = F)

Arguments

fit

A fitted model object containing tree structure and distance functions

chr

Character string specifying the chromosome

allele

Character string specifying the allele type

mu

Numeric value for the null hypothesis mean (default: 0)

sign

Logical indicating whether to use sign of delta values (default: FALSE)

Value

A tibble containing:

  • mean: Sample mean of delta values

  • chr: Chromosome identifier

  • allele: Allele type

  • p.value: P-value from t-test (NA if all values are identical)

  • greater: Logical indicating if mean > mu

Details

If all delta values are identical, no statistical test is performed and p.value is set to NA.
