Bivariate/cross-trait ld score regression

WebNULL can also be used to skip estimating standard errors, which is the default for snp_ldsc2 (). You can constrain the intercept to some value (e.g. 1). Default is NULL in snp_ldsc () (the intercept is estimated) and is 1 in snp_ldsc2 () (the intercept is fixed to 1). This is equivalent to parameter --intercept-h2. Websizes for trait Y 1 and Y 2,respectively;Ns is the number of overlapping samples; ρ is the phenotypic correlation between overlapping samples; and l(j,c) is the LD score of SNP j, defined as ljðÞ;c ≔∑ k∈c r2ðÞÞj;k [12]. The genetic covariance ρg is estimated by the slope obtained from a linear regression of β jγ on l(j,c). We can ...
