Published in 2022 at "American journal of epidemiology"

DOI: 10.1093/aje/kwac136

Abstract: There are important challenges to the estimation and identification of average causal effects in longitudinal data with time-varying exposures. Here, we discuss the difficulty in meeting the positivity condition. Our motivating example is the per-protocol… read more here.

Published in 2020 at "Statistical Methods in Medical Research"

DOI: 10.1177/0962280220975064

Abstract: We develop a joint modeling method for multivariate interval-censored survival data and a time-dependent covariate that is intermittently measured with error. The joint model is estimated using nonparametric maximum likelihood estimation, which is carried out… read more here.

Published in 2021 at "Applied Sciences"

DOI: 10.3390/app11104524

Abstract: Problems of digital processing of Poisson-distributed data time series from various counters of radiation particles, photons, slow neutrons etc. are relevant for experimental physics and measuring technology. A low-pass filtering method for normalized Poisson-distributed data… read more here.
