hematocrit_infants {httk}

Predict hematocrit in infants under 1 year old.

Description

For infants under 1 year, hematocrit was not measured in NHANES. Assume a log-normal distribution where plus/minus 1 standard deviation of the underlying normal distribution is given by the reference range. Draw hematocrit values from these distributions by age.

Usage

hematocrit_infants(age_months)

Arguments

age_months

Vector of ages in months; all must be <= 12.

Details

Age	Reference range
<1 month	31-49
