MMAPs to model complex multi-state systems with vacation policies in the repair facility
Juan Eloy Ruiz-Castro, Christian Acal
Two complex multi-state systems subject to multiple events are built in an algorithmic and computational way by considering phase-type distributions and Markovian arrival processes…
One cut-point phase-type distributions in Reliability. An application to Resistive Random Access Memories
Christian Acal, Juan Eloy Ruiz-Castro, David Maldonado +1
A new probability distribution to study lifetime data in reliability is introduced in this paper. This one is a first approach to a non-homogeneous phase-type distribution. It is b…
An approach to non-homogenous phase-type distributions through multiple cut-points
Juan Eloy Ruiz-Castro, Christian Acal, Juan B. Roldán
A new class of distributions based on phase-type distributions is introduced in the current paper to model lifetime data in the field of reliability analysis. This one is the natur…
A shiny app for modeling the lifetime in primary breast cancer patients through phase-type distributions
Christian Acal, Elena Contreras, Ismael Montero +1
Phase-type distributions (PHDs), which are defined as the distribution of the lifetime up to the absorption in an absorbent Markov chain, are an appropriate candidate to model the…
Functional ANOVA approaches for detecting changes in air pollution during the COVID-19 pandemic
Christian Acal, Ana M. Aguilera, Annalina Sarra +3
Faced with novel coronavirus outbreak, the most hard-hit countries adopted a lockdown strategy to contrast the spread of virus. Many studies have already documented that the COVID-…
logitFD: an R package for functional principal component logit regression
Manuel Escabias, Ana M. Aguilera, Christian Acal
The functional logit regression model was proposed by Escabias et al. (2004) with the objective of modeling a scalar binary response variable from a functional predictor. The model…
Basis expansion approaches for functional analysis of variance with repeated measures
Christian Acal, Ana M. Aguilera
The methodological contribution in this paper is motivated by biomechanical studies where data characterizing human movement are waveform curves representing joint measures such as…
Linear-Phase-Type probability modelling of functional PCA with applications to resistive memories
Juan E. Ruiz-Castro, Christian Acal, Ana M. Aguilera +2
Functional principal component analysis based on Karhunen Loeve expansion allows to describe the stochastic evolution of the main characteristics associated to multiple systems and…
Phase-type distributions for studying variability in resistive memories
Christian Acal, Juan E. Ruiz-Castro, Ana M. Aguilera +2
A new statistical approach has been developed to analyze Resistive Random Access Memory (RRAM) variability. The stochastic nature of the physical processes behind the operation of…
Homogeneity problem for basis expansion of functional data with applications to resistive memories
Ana M Aguilera, Christian Acal, M Carmen Aguilera-Morillo +2
The homogeneity problem for testing if more than two different samples come from the same population is considered for the case of functional data. The methodological results are m…
