adjust_LD               adjust LD for variable sample size
estprop                 Proportional colocalisation testing supplying
                        only a pair of regression coefficients.
estprop_slow            Proportional colocalisation testing
keep_from_S             keep snp subset of coloc dataset
lp                      logp
marg_with_V             create variance-covariance matrix for pair of
                        marginal beta + vbeta, given estimate of r
                        between snps
nform                   Helper function to adjust LD parameter r for
                        differential sample size between snps
plot_ellipses           draw two ellipses
run_proptests           run proportional tests on extreme subset of snp
                        pairs from two coloc style datasets. Of all
                        functions in this package, this is the main one
                        that should be used.
tag                     Derive tag SNPs using heirarchical clustering
tester_marg             run proportional test directly on marginal test
                        stats from coloc datasets
