Two-stage SuSiE-RSS Fine-mapping — fit_susie_inf_then_susie

RSS analog of fit_susie_inf_then_susie. Fits SuSiE-inf via susie_rss first, then initialises standard SuSiE-RSS from the SuSiE-inf result. The single pair of fits can be used both for fine-mapping post-processing and TWAS weight extraction.

Usage

fit_susie_inf_then_susie_rss(
  z,
  R,
  n,
  args = list(),
  susie_inf_args = list(),
  susie_args = list(),
  fitted_models = NULL
)

Arguments

z: Numeric vector of z-scores.
R: LD correlation matrix.
n: Sample size (scalar).
args: Default arguments forwarded to both fits.
susie_inf_args: SuSiE-inf-specific overrides.
susie_args: Standard SuSiE-RSS-specific overrides.
fitted_models: Optional list with pre-fitted $susie and/or $susie_inf objects to skip re-fitting.

Value

A list with susie and susie_inf fit objects.
