Estimate semi-exposure-response function (semi-ERF).
Source:R/estimate_semipmetric_erf.R
estimate_semipmetric_erf.Rd
Estimates the smoothed exposure-response function using a generalized additive model with splines.
Arguments
- formula
a vector of outcome variable in matched set.
- family
a description of the error distribution (see ?gam).
- data
dataset that formula is build upon Note that there should be a
counter_weight
column in this data.).- ...
Additional parameters for further fine tuning the gam model.
