Cool can u give us the form of the linear model?
sure. it's a multi-term model (engineering-kludge), where degrees of freedom
suffer and statistical validity is not the goal, just polishing the data is.
its designed to call a single chipd progeny with respect to the parents,
run per probe:
- B18*X_xpos < - these are the two youre interested in.
- B19*X_ypos < -
o where y is a borevitizian sfp-call using a non-permed t-test, empirically
set to force polymorphisms on about 10% of the chip (oversplitting)
o where the perfect match probes, mismatch probes, two parents, and progeny
are in the named terms, with the parents always ordered high-to-low (hence,
o where the gcp, tmp, ngp, xpos, and ypos are build with + in the sign, then
the sign is flipped at evaluation time.
o where the output is then split empirically, as well.
