On tests for sex preferences.
"This paper presents a critical evaluation of three widely used tests for sex preferences:  sex ratio, parity progression ratio and ordinary least squares [OLS] regression of birth interval.  We show that under some appropriate conditions, the sex ratio is a valid test for sex preferences.  The methods of parity progression ratio and OLS regression of birth interval fail to deal with right censoring and time varying covariates, which reduce the power of the tests.  We suggest the use of hazard estimation to test for sex preferences.  We demonstrate the differences among the tests by analyzing the retrospective fertility histories of the Chinese and the Malays in Malaysia.  We find that unlike the two conventional methods, the hazard estimation gives clear and strong evidence of sex preferences among the Chinese in Malaysia."
