Summary of results on frequency of cousin marriage and pool of potential partners. Total sample size of married adults for all these analyses n = 1310. The dashed lines separate analyses conducted with different statistical models. The parameters extracted for questions 2.2 and 2.3 are, respectively, the slope (β) and intercept (θ) coefficients related to the same predictor from the same model. The parameters extracted for question 3.2 pertain to the effects of two predictors in the same model. The estimates for questions 2.2, 2.3, 3.1 and 3.2 are from analyses with standardised predictors
