摘要
为了解影响突聋预后的主要因素,并对预后作出估计,我们对202例突聋患者用多元逐步判别和多元逐步回归分析。得出判别函数为:Y(1)=-6.9348559X2+6.1113288X3+1.5848862X5+1.1463944X6+3.7881483X8-20.910965Y(2)=-5.9508730X2+6.4491196X3+1.5484108X5+1.4552983X6+5.6799127X8-24.806810Y(3)=-6.8038957X2+6.510194X3+1.9272081X5+0.3147578X6+5.2027361X8-26.087992Y(4)=-6.3047006X2+6.1236259X3+2.2107182X5+0.2095116X6+4.84479538X8-23.862695其标准回归方程是:Y(g)=0.26836X8+0.26719X5+0.18007X6-0.07011X2。结果发现:耳聋程度、发病至治疗的时间和是否伴有眩晕对突聋的预后影响较大,且性别对突聋的预后亦有一定影响。判别函数和回归方程说明,耳聋越重、发病至治疗时间越长以及发病时伴有眩晕,其预后越差。在性别?
