To own Japanese–White pairing habits, i next reestimated the coefficients and you may chance rates towards sample excluding combat-fiance intermarriages
The term of interest is ? rR , from which the odds ratios were calculated. The constraints used in the two models for this effect are described below as design matrices. In the matrix, intermarriages between non-White groups were constrained to be equal (?step step one0). Models 1 and 2 differ by the specification of the interaction of husbands’ and wives’ race but include the same dimensions selected on the basis of findings in preliminary analyses. The simplified version of the structure of the models (Equation 1), with NrReEvG as the cell frequency, ?o as the intercept, and abbreviated indices and summation signs for categories in each dimension, is as follows:
Model 1 tests the significance of the influences of composition and educational pairing. A BIC value of less than 0 in Model 1 would indicate that the influences are statistically significant. This is because preliminary analyses showed that a simple model that includes only husbands’ race (? r ) and wives’ race (? R ) and their interaction term (? rR ), which excludes other measures from the model, yielded BIC values much greater than zero, which indicate a fit worse than the saturated model (with all multiway interaction effects). Model 2 tests the presence of gender asymmetry in the racial pairing patterns of the resettlement cohort. Intererican wives and White husbands might have become more common than intererican husbands and White wives after WWII. The War Bride Act could have legitimized the former type of intermarriage, and, in addition, had brought in intermarriages of Japanese war-brides and White veteran husbands from overseas. The ? rR terms of the two models, constrained differently with a design matrix to test for evidence of gender asymmetry, are presented in Appendix A (see Journal of ily online source). Each term in the cell represents a dummy variable. The cells with zeros are the omitted categories in the main effects of husbands’ and wives’ race Connecting Singles Dating. The off-diagonal cells of ? rR for non-White and non-White pairings are constrained to be equal to capture the effects of these rare intermarriages that are not the focus here. In the design matrix of Model 1, the dummy variable entries are symmetric around the diagonal cells of the table, which indicates gender symmetry. Model 2 includes two additional terms, namely ?11 for Japanese American wives and White husbands, and ?twelve for Japanese wives and White husbands, to account for gender asymmetry in the odds of intermarriage.
In the third and final step, we used the better-fit model to estimate the adjusted odds ratios. If Model 2 had a BIC value lower than that of Model 1 for one of the two cohorts, Model 2 was used to estimate both cohorts’ adjusted odds ratios for comparability across cohorts. From the coefficients, we calculated odds ratios by taking the exponent of the coefficients of interest in the design matrix-in the case of Model 2, those terms are ?1, ?3, ?4, ?seven, ?8, ?11, and ?12 (see Harris & Ono, 2005). For Japanese and Whites, for example, the odds ratios of homogamy versus intermarriage calculated from Model 2 are as follows: [exp(?1)exp(?4)]/(exp(?8+ ?12)exp(?8)].
War-bride intermarriages try intermarriages by White veteran husbands and you can Japanese wives regarding the resettlement cohort (n = step one,268, or 84% of Light partner and Japanese girlfriend lovers because cohort). That it exception to this rule would be to drastically raise the chances proportion with the resettlement cohort of your own Japanese’s combining patterns having Whites.

Appendix B (see Record off ily online resource) has got the regularity tables, from which i calculated the unadjusted opportunity ratios regarding homogamy in place of intermarriage getting lovers composed of Japanese or Japanese Us americans and Whites throughout the one or two wedding cohorts. Rates 1A and 1B let you know this new unadjusted possibility rates to possess Whites and you will Japanese People in the us and Whites and Japanese, respectively, toward a couple cohorts. Whether or not the combining try Japanese Americans which have Whites or Japanese that have Whites, whenever unadjusted, this new inclination to the homogamy atically toward resettlement cohort as compared to compared to this new prewar cohort. Especially, to own pairings out of Japanese People in the us with Whites regarding the postwar resettlement cohort, the odds percentages y try 410,100 times probably be versus likelihood of intermarriage through to the combat and you will 67,one hundred thousand times likely to be immediately after it. Having pairings away from Japanese with Whites, the newest postwar proportion y is actually 170,100000 times more likely than intermarriage until the battle and dos,900 minutes apt to be after they.
