Since NSFG hinges on an intricate decide to try (a good stratified, multistage structure that have personal testing costs), i used the computer software Stata to help you carry out screening from benefit to have get across-tabulations. 22
I used logistic regression to examine the connection of one’s features of women aged fifteen-17 into the likelihood one the male mate try step three-five years old otherwise half dozen or more decades avove the age of they was. The next logistic regression investigation looked whether the attributes of females therefore the decades difference in lady in addition to their partner assume play with from a contraceptive for a change sex.
