With a nominal ageing time, the joint had a ductile fracture mode; however, increased ageing time changed the joint to brittle fracture mode.
The fixed effects (b) of dam age in months, sex of the calf, and their interaction were considered by combining eight different first-calf age group classes (20 to 23, 23 to 25, 25 to 27, 27 to 29, 29 to 31, 31 to 33, 33 to 35, and 35 to 38 months) with sex of calf for a total of 16 nominal age-sex subclasses.
This is surprising as the feed is different, the mode of operation is different (continuous in parent vs sequenced in SBR), and at least 1 nominal sludge age occurred through the study.
This analysis involved construction of a non-linear model relating skin pigmentation (ordinal scale 2 = light, 1 = intermediate, 0 = dark), gender (nominal F/M), age (yrs), height (in), weight (lbs), and vitamin D daily dose (IU) to the observed serum vitamin D concentration obtained at the first blood draw.
Divergence time estimates for the Acacia thrips were inferred using a nominal root age of 1.
Group comparisons were based on Spearman's test for nominal variables (age, Ca125) and on the linear x-test for ordinal variables (stage, grading, complete/incomplete cytoreduction).
Unconditional logistic regression analysis was used to calculate odds ratios (ORs) and 95% confidence intervals (CIs), with adjustment for the possible confounders (gender as a nominal variable; age and pack-years of smoking, as continuous variables).
As can be seen, some of these criteria are measured on a binary scale (a tick indicates a disease is more prevalent among the poor than among the rich), nominal scale (age), ordinal scales (severity of disease), or ratio scale (cost-effectiveness).
In contrast, erosion rates at higher altitudes the semiarid Western Cordillera range up to 4600 cm/My (nominal exposure ages 0.02 0.1 My).
