Note. Numbers inside cells correspond to the number of participants' models that required the specific time-series parameter for prewhitening, with a maximum cell value of 24. Sqrt = Square root; (+) and (−) correspond to positive and negative linear trends, respectively; (Par) corresponds to a parabolic trend; Cycles of 2 and 4 correspond to 2 (half-day) and 4 (1 day) diary periods, respectively. For each cell, a maximum of 24 participants was possible except for obtained pleasure, in which a maximum of 23 was possible.
