This software estimates haplotypic frequencies from an input sample of genotypes, even with uncertainty, and it also analyzes the association between haplotypes and a response variable of binary, quantitative or survival type.

The theoretical issues in which BayHap is based on, belong to the frame of Bayesian statistics and MCMC techniques.

Given a sample of SNPs for a set of individuals, BayHap produces the following output:

• Estimated frequencies for each possible haplotype in the genotype sample.
  
• Standard errors for haplotypic frequencies.
  
• Estimated OR or HRR for each haplotype.
  
• Credibility intervals for each risk measure.
  

BayHap is being developed to run as a web tool (within SNPStats) and also as a package inside the R environment.
