Finally, regarding the multivariate endurance studies, Cox proportional possibilities regression investigation are utilized to assess danger percentages toward timing from intimate debut because of the gender; from the nature of your multistage testing construction, we produced robust standard mistakes in order to take into account you can easily clustering effects.

Abilities

To get per cent regarding participants have been aged fifteen–sixteen, while you are forty-two% was indeed 17–20 and you can 33% have been 21–24; half were male and you can 50 % of was people (Dining table 1, page 197).
