iDEMO (integrated
DEgradation MOdels)
R package version 0.3-1
Introduction
The package iDEMO
written in R and R GUI (graphical user interface) is a tool to build a
linear degradation model which can simultaneously consider the unit-to-unit
variability, within-unit variability and measurement error in the degradation
paths for the Wiener degradation-based processes. The gamma and inverse
Gaussian processes are considered as well. We provide the maximum likelihood
estimates (MLEs) of the unknown parameters, mean-time-to-failure (MTTF)
and qth quantile, and their corresponding confidence intervals based on
the different information matrices. In addition, degradation model selection
and goodness-of-fit tests are provided to determine and diagnose the degradation
model for the user's current data by the commonly used criteria. By only
enabling user interface elements when necessary, input errors are minimized.
