Distributional data analysis of accelerometer data from the NHANES database using nonparametric survey regression models
نویسندگان
چکیده
Abstract The aim of this paper is twofold. First, a new functional representation accelerometer data distributional nature introduced to build complete individualized profile each subject’s physical activity levels. Second, we extend two nonparametric regression models, kernel smoothing and ridge regression, handle survey obtain reliable conclusions about the influence activity. advantages proposed are demonstrated through various analyses performed on NHANES cohort, which possesses complex sampling design.

Estimating Distribution Functions from Survey Data Using Nonparametric Regression
Survey sampling often supplies information about a study variable only for sampled elements. However, auxiliary information is often available for the entire population. The relationship of the auxiliary information with the study variable across the sample allows inferences about the nonsampled portion of the population. Thus, auxiliary information can be used to improve upon survey estimation...
متن کاملA New Nonparametric Regression for Longitudinal Data
In many area of medical research, a relation analysis between one response variable and some explanatory variables is desirable. Regression is the most common tool in this situation. If we have some assumptions for such normality for response variable, we could use it. In this paper we propose a nonparametric regression that does not have normality assumption for response variable and we focus ...
متن کاملEstimation of Count Data using Bivariate Negative Binomial Regression Models
Abstract Negative binomial regression model (NBR) is a popular approach for modeling overdispersed count data with covariates. Several parameterizations have been performed for NBR, and the two well-known models, negative binomial-1 regression model (NBR-1) and negative binomial-2 regression model (NBR-2), have been applied. Another parameterization of NBR is negative binomial-P regression mode...
