Prediction of financial distress base on Multivariate Discriminant and effectiveness of efficiency score in improvement of model

In this research Multivariate Discriminant Analysis used as an effective model for pridiction of financial distress and noticed to ability of efficiency in improvement of model. At the first financial distress prediction model were designed base on Multivariate Discriminant Analysis by financial ratios variables of sample corporations in 1999 to 2008 years. Then for specifying ability of efficiency score variable in prediction of financial distress, we were designed financial distress prediction model base on Multivariate Discriminant Analysis with financial ratios and efficiency score. The results show that models are able to predict financial distress of production corporations in Tehran stock exchange two years prior to its occurrence. The results of two models and compare of them show that although efficiency score variable can better the results of financial distress prediction model but the different between accuracy predictions of financial distress in two models is not important.
