Discussion

  • body temperature is guessed
  • males are supposed to differ from females by {p_Am} only
  • mod_1: v is reduced
  • mod_2: Pseudo-data point k is used, rather than k_J; Data set tp and parameter t_R are added, the latter replacing clutch interval t_N. Postnatal T is based on PrinPres1991, see get_T_Aves. See further the revision page, theme puberty
  • mod_3: data sets Ww0, Wwx are added
