WebJun 3, 2024 · Accumulating evidence from genome wide association studies (GWAS) suggests an abundance of shared genetic influences among complex human traits and disorders, such as mental disor 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.
