Frailty Index as a Major Indicator of Aging Processes and Mortality in Elderly: Results From Analyses of the National Long Term Care Survey Data
A. Kulminski, A. Yashin, I. Akushevich +4
To better understand mortality change with age capturing the variability in individuals' rates of aging, we performed comprehensive analysis of statistical properties of a cumulati…
Age-Associated Disorders As A Proxy Measure Of Biological Age: Findings From the NLTCS Data
A. Kulminski, A. Yashin, S. Ukraintseva +4
Background: The relative contribution of different aging-associated processes to the age phenotype may differ among individuals, creating variability in aging manifestations among…
Linear Latent Structure Analysis: from Foundations to Algorithms and Applications
I. Akushevich, M. Kovtun, A. I. Yashin +1
A new statistical technique for constructing linear latent structure (LLS) models from available data, supported by well established theoretical results and an efficient algorithm,…
Linear Latent Structure Analysis: Mixture Distribution Models with Linear Constraints
Mikhail Kovtun, Igor Akushevich, Kenneth G. Manton +1
A new method for analyzing high-dimensional categorical data, Linear Latent Structure (LLS) analysis, is presented. LLS models belong to the family of latent structure models, whic…
A New Efficient Algorithm for Construction of LLS Models
Mikhail Kovtun, Igor Akushevich, Kenneth G. Manton +1
We present a new efficient algortithm for construction of linear latent structure (LLS) models. This algorithm reduces a problem of estimation of model parameters to a sequence of…
Grade of Membership Analysis: One Possible Approach to Foundations
Mikhail Kovtun, Igor Akushevich, Kenneth G. Manton +1
Grade of membership (GoM) analysis was introduced in 1974 as a means of analyzing multivariate categorical data. Since then, it has been successfully applied to many problems. The…
