For each control unit, treats it as pseudo-treated and fits SCM weights
from the remaining N_co-1 donors. Returns MSPE components for constructing
MSPE-ratio permutation p-values in R.
Usage
scm_placebo_cpp(Y_pre, Y_post, max_iter = 100L, tol = 1e-04)
Arguments
- Y_pre
Control pre-treatment outcomes (T_pre x N_co)
- Y_post
Control post-treatment outcomes (T_post x N_co)
- max_iter
Outer coordinate-descent iterations (default 100)
- tol
Convergence tolerance for V updates (default 1e-4)
Value
A list with:
mspe_pre: N_co-vector of pre-treatment MSPE per placebo unit
mspe_post: N_co-vector of post-treatment MSPE per placebo unit
effects: N_co-vector of mean post-period gap per placebo unit
