Abstract
Regression analysis is one statistical tests commonly used for multifactorial data analysis. Regression analysis is interesting to use theoretically as it is based on mathematics. In addition, this analysis can be employed to investigate and model relations between variables. Regression analysis can be applied in variousdisciplines, such as engineering, physics, economics, management, biological and social sciences. Problem that most commonly found in health data is that they do not fulfill the classical assumptions. Such problem may be overcome by means of regression analysis that is not bound to an_v assumptions, such as regression trees method and Cox regression analysis. This study was aimed to survival data analysis (analyze factors affecting the length of hospitalization of underwifes with diarrhea) using regression trees method and Cox regression method. Data used in this study were those on the length of hospitalization of underfives with diarrhea in Dr Soetomo Hospital. The number of data in this study was 586, 57 of which were censored data, and the remaining 529 uncensored. The cross validated relative error was 0.922 ±0.041, the resubstitution relative error was 0.696 and the complexity was 45.497, the independent variables affecting the length of hospitalization in underfives with diarrhea, as revealed by means of regression trees method, were length of diarrhea, accompanying disseases, nutritional status, and dehydration, while variables affecting the length of hospitalization in underfives with diarrhea, as indicated by means of Cox regression method of a = 0.05, were length of diarrhea, accompanying diseases, and nutritional status.
