Webb22 dec. 2010 · The simple ℳ method is currently the fastest way to calculate the effective number of independent tests in a GWAS [ 32 ], but due to the O ( n2) nature of this algorithm the genome needs to be broken up into small regions to maintain this computational speed. This adds complexity to the analysis and requires a significant … WebbHence, GWAS is a non-candidate-driven approach, in contrast to gene-specific candidate-driven studies.
