Sistema computacional para ajuste de funções densidade de probabilidade

Abstract

This study aimed to initiate, implement and validate a project to build a computerized system to adjust probability density functions. The FitFD was developed using the Java programming language. IDE (Integrated Development Environment) NetBeans 7.1 and JDK 7.3 (Java Development Kit) were used as the development environment. The system was tested in Windows. The following probability density functions were implemented in the system: Weibull (2P, 3P, 2P with minimum dbh, truncated 3P), hyperbolic (2P, 3P, 2P with minimum dbh, truncated 3P), Log- logistic (2P, 3P, 2P with minimum dbh), Logistics Generalized, Fatigue Life (2P and 3P) and Frechet (2P and 3P) . The system developed assists users in defining and choosing fdp that best meet their needs, however improvements are needed. The project proved efficient for adjustments of probability density functions.
