gen_serum_creatinine {httk} | R Documentation |
Generate serum creatinine values for a virtual population.
Description
Predict serum creatinine from age using smoothing splines and kernel density estimates of residual variability fitted to NHANES data,, for a given combination of gender and NHANES race/ethnicity category.
Usage
gen_serum_creatinine(gender, reth, age_years, age_months, nhanes_mec_svy)
Arguments
gender |
Gender for which to generate serum creatinine values ("Male" or "Female") |
reth |
NHANES race/ethnicity category for which to generate serum creatinine values ("Mexican American", "Non-Hispanic Black", "Non-Hispanic White", "Other", or "Other Hispanic") |
age_years |
Vector of ages in years for individuals for whom to generate serum creatinine values (corresponding to age_months) |
age_months |
vector of ages in months for individuals for whom to generate serum creatinine values (between 0-959 months) |
nhanes_mec_svy |
|
Details
This function should usually not be called directly by the user. It is used
by httkpop_generate()
in "virtual-individuals" mode, after drawing
gender, NHANES race/ethnicity category, and age from their NHANES
proportions/distributions.
Value
A vector of numeric generated serum creatinine values (mg/dL).
