Bankruptcy prediction is an important research topic. The cost of incorrect decision making in companies and financial institutions can be great and could affect large parts of society. But while it is indeed a major research area, there are few studies which consider the effects of feature selection. This is an important step that could improve the performance of bankruptcy prediction models. This thesis therefore aims to find which feature selection methods perform best for bankruptcy prediction. Five feature selection methods will be compared and used to create datasets with fewer redundant features. To test these methods, a LSTM model is used to train on both an unaltered dataset and datasets created by the mentioned models. The predictive performance of these are then compared with the metrics AUC, Type I error, and Type II error. This study finds that the forward selection algorithm from the Stepwise regression method performed best with an increase in AUC score and decrease in both Type I and Type II error rates compared to the model trained on the unaltered dataset.
