PLINK1 --missing: per-sample (.imiss) and per-variant (.lmiss)
genotype missingness.
A genotype is missing iff its packed 2-bit code is 0b01. Per sample we
report N_MISS / N_GENO (= variant count) / F_MISS; per variant N_MISS /
N_GENO (= sample count) / F_MISS. F_MISS is N_MISS / N_GENO, printed with
C %g. Unlike --het, every variant is reported regardless of chromosome.
