dc:description "Downloaded the AnAge build-15 zip and parsed anage_data.txt. Maturity age is the mean of the positive female and male values present. The three named binomials were compared with the pre-registered inequalities. Among Mammalia rows with positive adult weight, growth rate and maturity age, OLS of ln(adult weight) on ln(growth rate) and ln(maturity age) was compared with each one-predictor model by partial t-tests and AIC. No species was dropped as an outlier. The verdict is the pre-registered rule applied to those quantities.";
<http://www.w3.org/2000/01/rdf-schema#comment> "Measured: undefined undefined. Interpretation: Thompson (1917, ch. III), quoting Minot: final size is a resultant of rate and duration; the rabbit is bigger than the guinea-pig because it grows faster, and man is bigger than the rabbit because he grows for longer. 'Size finally attained' is AnAge adult weight. 'Rate' is the database's fitted postnatal growth-rate constant, not a rate recomputed from adult weight and age (that recomputation would make the decomposition an identity). 'Duration of growth' is proxied by age at sexual maturity, the duration field the compilation actually carries; age at growth cessation is not in the file. The mammal regression asks whether both factors associate with adult mass beyond the three named species. It does not identify a causal mechanism, and a fitted growth constant can be partly entangled with asymptotic size.";

<https://w3id.org/delphi/ontology/evidenceAgainst> "A fitted growth constant can be entangled with the adult mass it is asked to explain. These are species-level database values, not individual growth curves.",
"Age at sexual maturity stands in for duration of growth. AnAge has no age at cessation of growth. For humans the recorded maturity ages are about 13 and 14 years, not the age at adult stature.",
"The European rabbit row has no male maturity age, so its duration is the female value alone.",
"The growth-rate column is a specific constant in 1/days, not grams gained per day. Across the 243 mammals its partial slope on ln adult mass is negative, so larger species have slower specific rates. An absolute mass-gain reading of 'grows the faster' was not tested.",
"The rabbit is faster than the guinea pig, as the contrast required, and also matures about ten times later. The pre-registered contrast does not require rate to be the larger factor.",

REFUTES if either weight ordering is reversed (W_rabbit < W_guinea-pig or W_human < W_rabbit), or the rabbit is heavier but not faster (W_rabbit > W_guinea-pig and k_rabbit < k_guinea-pig), or the human is heavier but does not mature later (W_human > W_rabbit and T_human < T_rabbit), or the human is heavier and matures later but also has k_human > k_rabbit, or (n >= 40 and both partial slopes are <= 0). MIXED if the rows are scorable and the outcome is neither SUPPORTS nor REFUTES, including a case in which the named contrasts hold but the joint test does not, or only one named contrast holds. A tie in a required strict inequality makes that contrast fail. INCONCLUSIVE reason data-unavailable if the AnAge zip cannot be fetched or a named species lacks W or k, or lacks T when the contrast needs T. INCONCLUSIVE reason underpowered if both contrasts are scorable, neither refutation clause has fired, and n < 40 so the joint test cannot be scored: the verdict is then SUPPORTS if both contrasts hold, MIXED if only one holds, and is not underpowered.";

<https://w3id.org/delphi/ontology/inferenceMethod> "Two directional species contrasts as stated by Thompson, plus OLS of log adult mass on log growth rate and log maturity age compared with the two nested one-predictor models by partial t-tests (p < 0.05) and AIC (delta >= 2).

Named rows are the exact binomials Homo sapiens, Oryctolagus cuniculus and Cavia porcellus (Genus + species). Rabbit–guinea-pig holds if W_rabbit > W_guinea-pig and k_rabbit > k_guinea-pig. Human–rabbit holds if W_human > W_rabbit and T_human > T_rabbit and k_human < k_rabbit.

Joint holds if n >= 40, both slopes are > 0, both two-sided t p-values are < 0.05, and the two-predictor AIC is at least 2 lower than the AIC of each one-predictor model (log k alone, and log T alone), with AIC = n*ln(RSS/n) + 2*p including the intercept.
