AFLPsim (version 0.4-2)

hybridindex: Estimate hybrid index por hybridsim objects

Description

This function finds maximum likelihood estimates of hybrid index as described by Buerkle (2005) using the packages introgress

Usage

hybridindex(data)

Arguments

data

an hybridsim object with the profiles of parentals and hybrids.

Value

• A data frame with estimates of hybrid index and upper and lower limits of its 95% confidence intervals, which falls within two support units of the maximum-likelihood estimate:
• lower
  95% confidence interval lower limit.
• h
  Maximum-likelihood estimate of the hybrid index.
• upper
  95% confidence interval upper limit.

Details

hybridindex returns a hybrid index estimate with its 95% confidence interval. See est.h and Buerkle (2005) for additional details.
