Goodness-of-fit test for the AFT model based on martingale residuals
Novák, Petr
The Accelerated Failure Time model presents a way how to easily describe survival data with regression on covariates. It is assumed that each observed unit ages internally faster or slower, depending on the covariate values. To use the model properly, we want to check if observed data fit the model assumptions. In the present work we introduce a goodness-of-fit statistics based on modern martingale theory. On simulated data we try to estimate empirical properties of the test for various situations.

Toolbox Jobcontrol s GUI
Novák, Miroslav ; Tesař, Ludvík
Jobcontrol is a toolbox merging a user-friendly graphical user interface with a powerful set of utilities for system identification employing Gaussian mixture model. It is implemented as a set of M-scripts and MEX-binary executables for the Matlab computing environment. It suits to the goal of finding a suitable structure for the given data and then it creates the optimal controller by tuning its parameters to fit the user's requirements.
