In OxWearables/epicoda: Supports epidemiological analyses using compositional exposure variables

Extract compositional mean from model object

Description

Used by predict_fit_and_ci and plot_transfers.

Usage

get_cm_from_model(model, comp_labels, transf_labels)

Arguments

model	Model to use in estimates/predictions.
comp_labels	The labels of the compositional columns.
transf_labels	Ilr-transformed compositional column labels.

Value

Compositional mean of data used to create models, on both original and transformed scale (two element list).

Examples

lm_outcome <- comp_model(
type = "linear",
outcome = "BMI",
covariates = c("agegroup", "sex"),
data = simdata,
comp_labels = c("vigorous", "moderate", "light", "sedentary", "sleep"),
det_limit = 0.00119
)

comp_labels <- c("vigorous", "moderate", "light", "sedentary", "sleep")
tl <- transf_labels(comp_labels = comp_labels, transformation_type = "ilr")
get_cm_from_model(model = lm_outcome, comp_labels = comp_labels,
transf_labels = tl)
