Observed and unobserved heterogeneity in failure data analysis
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-06-08)

Heterogeneity can be classified as observed and unobserved heterogeneity. Un-observed heterogeneity is the effect of unknown, unrecorded, or missing covariates. In most reliability studies, the effect of unobserved covariates is neglected. This may lead to inaccurate ...
