Anencephaly in Japan: paternal age, maternal age and birth order. 1979

Y Imaizumi

The statistical association between incidence of anencephaly and paternal age, maternal age and birth order was analysed in 1815 cases of foetal deaths with anencephaly reported during 1975--6. The birth order association was confirmed with an extremely high degree of statistical significance.

D012044	Regression Analysis	Procedures for finding the mathematical function which best describes the relationship between a dependent variable and one or more independent variables. In linear regression (see LINEAR MODELS) the relationship is constrained to be a straight line and LEAST-SQUARES ANALYSIS is used to determine the best fit. In logistic regression (see LOGISTIC MODELS) the dependent variable is qualitative rather than continuously variable and LIKELIHOOD FUNCTIONS are used to find the best relationship. In multiple regression, the dependent variable is considered to depend on more than a single independent variable.
