coeff

Part of the set of internal functions called within the <code>tvmcurve_3trt</code> function 
to assist in the estimation of time varying mediation effect.

Provides functions for estimating mediation effects that vary over
time as described in Cai X, Coffman DL, Piper ME, Li R.
Estimation and inference for the mediation effect in a time-varying mediation model.
