extract_nzv_mh: Extract medical history without zero variance

In herdiantrisufriyana/medhist: A preprocessor to construct medical history table from data source

Description

This function makes a list of medical histories without zero variance.

Usage

extract_nzv_mh(tidy_set, sd_cutoff = 0)

Arguments

tidy_set	A TidySet (i.e. ExpressionSet) containing the visits of subjects in outcome dataset, paid by any payment systems. This TidySet also accomodates outcome dataset. This is an output of compile_mh_outcome().
sd_cutoff	Cutoff of standard deviation, a non-negative numeric that is used for cutoff. If standard deviation of a medical history metric is more than the cutoff, then that medical history is accounted to the list.

Value

Medical history list, a data frame with rows for unique medical history and columns of key and sd_value. Missing value or NA is not accounted when computing the standard deviation.
