Testing effects of HCW class on estimates of T0 and k for temperature decline of the ham1
Estimate2 | SE | P-value3 | |
---|---|---|---|
T 0 | |||
85 kg | 40.73 | 0.20 | <0.0001 |
(+/− compared with estimate of 85 kg) | |||
90 kg | +5.64 | 1.74 | <0.01 |
95 kg | +8.21 | 2.27 | <0.01 |
100 kg | +7.60 | 2.31 | <0.01 |
105 kg | +10.06 | 2.78 | <0.01 |

90 kg | −0.00023 | 0.00028 | 0.40 |
95 kg | −0.00020 | 0.00029 | 0.50 |

ρ1 | 1.88 | 0.03 | <0.0001 |
ρ2 | −0.88 | 0.03 | <0.0001 |
1 T 0 is the initial temperature measured in °C, k is the fractional rate constant, ρ1 is the first-order lag, and ρ2 is the second-order lag.
2Parameter estimates corresponding to the 85-kg class were considered the control. Values presented in the estimate column corresponding to 90 to 105 kg classes are adjustments compared to the parameter estimated for 85-kg class.
3All P values represent to probability that the estimate is equal to zero. For adjusted estimates, significant P values indicate that the parameter estimate for that weight class is different from the 85 kg class.
*The parameter estimate is different from zero (P ≤ 0.05). Lags (ρ1, ρ2) were not adjusted for HCW.
