1241. The AstroStat Slog Blog Archive The Flip Test
... Why is it that detection of emission lines is more reliable than that of absorption lines? ... When you look at the iconic Figure 1 from Protassov et al (2002) , which shows how the null distribution of the Likelihood Ratio Test (LRT) and how it holds up for testing the existence of emission and absorption lines. The thin vertical lines are the nominal F-test cutoffs for a 5% false positive rate. ... Tags: absorption line , emission line , F-test , LRT , Protassov , question for statisticians . ...

1246. The AstroStat Slog Blog Archive Is 3sigma the same as 3*1sigma?
... Sometime early this year, Jeremy Drake asked this innocuous sounding question in the context of determining the bounds on the amplitude of an absorption line: Is the 3sigma error bar the same length as 3 times the 1sigma error bar? In other words, if he measured the 99.7% confidence range for his model parameter, would it always be thrice as large as the nominal 1sigma confidence range? ... That о?^2 function does not explain the error of the parameter estimator unless the model is linear. ...
