<H2>Overview </H2>
<p>
Heritability Calculator (HC) is a set of utilities used for computing
	heritability for different genetic architectures, for designing association studies, 
	for calculating power of association studies, and for studying the influence of population genetics on association. 
	Using the package, one can explore different architectures, compute relevant genetic and epidemiological parameters 
	such as narrow-sense and broad-sense heritabilities, the heritabilities estimated from population
	studies, risk to relatives, genetic relative risk, compute power for single-SNP and aggregate tests, simulate the 	
	allelic frequency spectrum as a function of selection etc. 

	The package also includes routines for power calculation for 
	SNPs main effect and epistasic relations.

	You can also use the package to simulate of a population from a 
	founder population and estimate heritability using IBD sharing. 	

	 Detailed instructions and usage examples
	are given in the <a href="README.txt"> README</a> file.
