| Popis: | 100 This paper uses logistic regression and neural network to examine whether the companies had the financial crises during and after the periods of Financial Tsunami by collecting data from the listed companies in Taiwan. We choose 26 independent variables initially and then use recursive feature elimination based on support vector machine to select the important variables from the original 26 variables. After selecting the important variables, we use logistic regression and neural network again to determine the correct rates of prediction. Our empirical results indicate neural network methods are better than logistic regression, no matter which the sample period is. The recursive feature elimination based on support vector machine is a good feature selection. The correct rates increase, when the sample periods close to the timing of financial crises or the sample periods lengthen. |
