Description Usage Arguments Value References Examples

Returns a *Zbeta* value for each SNP location supplied to the function.
For more information about the *Zbeta* statistic, please see Jacobs (2016).
The *Zbeta* statistic is defined as:

*Z_{β}=\frac{∑_{i \in L,j \in R}r^2_{i,j}}{|L||R|}*

where `|L|`

and `|R|`

are the number of SNPs to the left and right of the current locus within the given window `ws`

, and *r^2* is equal to the squared correlation between a pair of SNPs

Minimum number of SNPs in each set R and L for the statistic to be calculated. Default is 4. |

Minimum value for the product of the set sizes for R and L. Default is 25. |
