below the baseline level of risk was 1.73 times larger or smaller than the average likelihood of marriage. Said another way, one’s individual likelihood of marriage increases when they are genetically more similar to others who are married, and decreases when they are genetically more similar to others who are unmarried. The variance component associated with the familial environment random effect was 0.30 (SD = 0.54). This corresponds to a relative risk of marriage that is 1.72 higher or lower than the baseline hazard rate, meaning that the family-specific relative risk of marriage was 1.72 times larger or smaller than the average likelihood of marriage for families who are one standard deviation above or below the baseline level of risk. In other words, likelihood of being married (or not) clusters within families.
