In clikcorr: Censoring Data and Likelihood-Based Correlation Estimation

Description

ND is an example data set extracted from National Health and Nutrition Examination Survey (NHANSE). The data set contains 100 samples and IDs and upper and lower bounds for 22 chemical compounds, including 7 dioxins, 9 furans, and 6 PCBs.

Usage

data(ND)

Format

A data frame with 1643 observations and 45 variables. Variables contain SEQN: ID; t1_TCDD: lower bound for dioxin TCDD; t2_TCDD: upper bound for dioxin TCDD; ... t1_PCB_189: lower bound for PCB_189 and t2_PCB_189: upper bound for PCB_189.
