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?
To understand the main factors that affect the prognosis of sudden deafness and to estimate the prognosis, we used multivariate stepwise discriminant analysis and multivariate stepwise regression analysis on 202 patients with sudden deafness. The discriminant function is obtained as follows: 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 The standard regression equation is: Y (g) = 0. 26836X8 + 0 26719X5 + 0.18007X6-0.07011X2. The results showed that: the degree of deafness, the time from onset to treatment and whether or not dizziness have a significant effect on the prognosis of sudden deafness, and the gender has a certain impact on the prognosis of sudden deafness. Discriminant function and regression equation shows that the more severe deafness, onset to treatment longer and associated with dizziness, the worse the prognosis. In gender?
