Discussion

  • Males are assumed to differ from females by {p_Am} only
  • In view of low somatic maintenance, pseudodata k_J = 0.002 1/d is replaced by pseudodata k = 0.3
  • LdL data is assumed to represent relative growth in percent per yr, rather than mm/yr, since von Bert is reported to fit well; the resulting time since birth ar puberty is 14 yr, rather than the ignorved 5.3 yr
