[GenABEL-dev] Precision and scientific notation in ProbABEL

[L.C. Karssen]

Dear list,

I'm finalising version 0.4.0 of ProbABEL and there are two things I'd
like your opinion on:

1) with what precision should we print the betas, standard errors and
Chi^2 values to the output files?

2) Should we use scientific notation in the output (for betas, standard
errors and Chi^2)?

In ProbABEL v0.3.0 and earlier output was simply sent to cout without
any explicit formatting. In practice this lead usually to 6 significant
digits, but sometimes less. My proposal is to fix the precision at 6
significant digits.

Regarding item 2): most of the betas I see are in the range between 0
and 10, although in case of no effect beta's can be of the order of
1e-2, 1e-3. All in all, I don't think switching to scientific notation
will improve the output.


What are your opinions?


Thanks,

Lennart.
