Markov switching regression processes belong to the class of Hidden Markov models (HMMs). They provide a higher flexibility than, for example, simple (auto)regression. The main reason for their popularity is the convenient interpretability. For sufficiently long time series, the different...

Mean residual life function, or life expectancy, is an important function to characterize distribution of residual life. The proportional mean residual life model by Oakes and Dasu (1990) is a regression tool to study the association between life expectancy and its associated covariates....

Quasi-independence is a common assumption for analyzing truncated data. To verify this condition, we propose a class of weighted log-rank type statistics that includes existing tests proposed by Tsai (1990) and Martin and Betensky (2005) as special cases. To choose an appropriate weight function...
