We address three timely regression analysis problems in solar-terrestrial observations: the identification of trends in observations that exhibit a high level of internal variability, the choice of explanatory variables in the multilinear regression of climate data, and the identification of power laws in power spectral densities. In all three of them we focus on some common mistakes, and on how these may help facilitate critical reading of research in the field.
