WebNational Center for Biotechnology Information 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. t statistic regression formula
