The intercept-only parameters for both trend function and GP for females in Table A are nearly identical
to those for males in Table 4.1 as well as the GP parameters for the quadratic model. The quadratic trend
function parameters are much dierent for males and females. In particular, the intercept terms are all
much dierent in magnitude, and some of the higher order terms dier in sign. This is likely an indication
that the trend curves diers in shape between genders in their respective age groups, which is unsurprising
since the age group endpoints were chosen to match the male dataset
