... The work with untriggered flare searches is ongoing, but I'm still working on more checks for applications of the method beyond one point. The goal is an all-sky search for flares. For triggered flares, the lightcurve method is outlined here and I think it's ready to go. There are also several flar ...

... Methods for dealing with unequal variance: a. Transform the response variable: Replace Y with h(Y), so that the model becomes • h(Yit) = µ* + τi* + εit* • The εit*'s are independent random variables. • For each i and t, εit* ~ N(0 , σ2) (More on this later) b. Use a method such as Satterthwaite's (p ...
