[Use of discrimination analysis in perinatology]

From 50 normal births blood of mother and child was examined simultaneously at three different times, meant for determination of 13 biochemical parameters. Evaluation of the measured values was done by the multivariate method of discriminance analysis. Basing on the observed data problems of discriminance analysis are dealt with in an introductive way. The perinatal example is used to demonstrate how in the case of a complex problem connections may be better visible by this method, though detailed informations are lost.
