Mediation analysis in longitudinal intervention studies with an ordinal treatment-dependent confounder
Mikko Valtanen, Tommi Härkänen, Matti Uusitupa +3
In interventional health studies, causal mediation analysis can be employed to investigate mechanisms through which the intervention affects the targeted health outcome. Identifyin…
Adjusting for selective non-participation with re-contact data in the FINRISK 2012 survey
Juho Kopra, Tommi Härkänen, Hanna Tolonen +4
Aims: A common objective of epidemiological surveys is to provide population-level estimates of health indicators. Survey results tend to be biased under selective non-participatio…
Dynamic Modeling in Health Research as a framework for developing statistical applications free of misuse of statistics
Vladislav Moltchanov
We introduce a novel framework for developing statistical applications in health research, based on dynamic modeling of the investigated processes. We formulate the principles of d…
Characterizing the generalized lambda distribution by L-moments
Juha Karvanen, Arto Nuutinen
The generalized lambda distribution (GLD) is a flexible four parameter distribution with many practical applications. L-moments of the GLD can be expressed in closed form and are g…
Efficient initial designs for binary response data
Juha Karvanen
In this paper we introduce a binary search algorithm that efficiently finds initial maximum likelihood estimates for sequential experiments where a binary response is modeled by a…
