To illustrate susie itself
¶
[] How susie behaves when the top SNP is not the causal signal.
[] How susie copes with subtle difference in tightly correlated variants.
with SER is perhaps enough, and provide some back-of-envelope BF computations.
Look in N = 1 simulations of high LD > 0.95, PIP difference > 0.8. This may also indicate small difference in z-score anyways.
[] Independent signals in high LD region.
[] Small size yet low purity.
[] Show susie iteration gradual convergence.
Look in N = 2 simulations of small CS size yet large number of iterations.
[] Show why susie can pick up one variable twice.
[] Show why susie captures two same signals in two iterations.
To illustrate susie with other methods
¶
[X] A vignette showing finemapping analysis with other methods and compare PIP results with susie
[] Comparison of susie iterations with step-wise conditional regression.
[] Comparison of susie with SER. This would be a special case of above.
Questions
¶
Issues in reporting independent signals: duplicated? near by clusters? Should assess correlation between CS before reporting and how?
How does multiple-testing come into play here?
How does the prior setting actually reflects prior on number of causal as FINEMAP does it?
