Bivariate log-symmetric models: distributional properties, parameter estimation and an application to fatigue data analysis
Roberto Vila, Narayanaswamy Balakrishnan, Helton Saulo +1
The bivariate Gaussian distribution has been a key model for many developments in statistics. However, many real-world phenomena generate data that follow asymmetric distributions,…
Unit-log-symmetric models: Characterization, statistical properties and its use in analyzing internet access data
Roberto Vila, Narayanaswamy Balakrishnan, Helton Saulo +1
We present here a unit-log-symmetric model based on the bivariate log-symmetric distribution. It is a flexible family of distributions over the interval . We then discuss i…
Robust inference for non-destructive one-shot device testing under step-stress model with exponential lifetimes
Narayanaswamy Balakrishnan, Elena Castilla, María Jaenada +1
One-shot devices analysis involves an extreme case of interval censoring, wherein one can only know whether the failure time is either before or after the test time. Some kind of o…
