In bjb40/bioage: Klemera-Doubal biological age algorithm.

Description

Project from a training dataset into a validation dataset using kdm or hd algorithms.

Usage

project(training_data, projection_data, method = "hd", biomarkers, ...)

Arguments

training_data	The dataset for calculating biological age or hd.
projection_data	The dataset for projecting biological age or hd into.
method	A character variable of either 'hd' or 'kdm' to identify the
biomarkers	A character vector indicating the names of the variables for the biomarkers to use in calculating biological age.
filter	a list with biomarker names that identifies any restrictions in training data. See vignette or data description for example of use.

Value

An object of class 'kdm' or 'hd'. This object is a list with two elements (data and fit), and two methods (extract_data and extract_fit). Data is limited to the "projection" dataset. Fit is calculate from "training" dataset.

Examples

#(not run)
#Train biological age parameters
ndata = project(training_data=nhanes,projection_data=holdout,
                agevar='age',
                biomarkers=c('sysbp','totchol','bun','cmv','mcv'))
