Ldak-thin model
Full details of all heritability models are provided in Supplementary Tables 13 and 14. The one-parameter GCTA model2 (the default model of both the GCTA and LDSC software) assumes E[h2j] = τ1. The GCTA-LDMS-R7 and GCTA-LDMS-I8models both take the form where Ijk indicates whether SNP j is in bin k. … Meer weergeven The heritability model describes how the expectation of h2jvaries across the genome. We first assume the model takes the form … Meer weergeven The authors of LDSC3 derived that each Sj approximately follows a scaled χ2(1) distribution with scale factor E[Sj] (or equivalently, a gamma distribution with shape 1/2 and … Meer weergeven To date LDSC and SumHer have required that the heritability model be linear (this ensures that E[Sj] can be expressed as a linear … Meer weergeven LDSC estimates the parameters of the heritability model using weighted least-squares regression3, with regression weights 1/uj × 1/(2E[Sj]2); weighting by 1/uj allows for correlations between nearby SNPs … Meer weergeven Web15 aug. 2024 · The one-parameter LDAK-Thin Model is a simplified version of the LDAK Model, obtained by setting the LDAK weightings to either one or zero.
