PPT-Methods for reconstructing or estimating stellar Lyman-α and EUV fluxes

Jeffrey Linsky JILA and APAS Solar Focus Group April 12 2019 Why are the Lymanα and EUV fluxes important Lymanα is the brightest line in the solar UV spectrum Lymanα is as bright as the entire UV spectra of M dwarf stars. Although these methods are somewhat harder to describe and implement several econometrics packages sup port them In Section 141 we discuss the fixed effects estimator which like first differencing uses a transformation to remove the unobserved effec Fraction.
