Under the generate_weights() command using the {tidysynth} package for executing the synthetic control method in R, users are given a number of optimization options. However, I cannot find documentation on what these optimization options do as {tidysynth} is no longer supported on CRAN (if anyone knows why, I would also like to know that as well).
You can still access reference material for {tidysynth} on GitHub and it has the following code as an example of their optimization options:
generate_weights(optimization_window = 1935:1949,
margin_ipop = .02, sigf_ipop = 7, bound_ipop = 6)
Barring the optimization_window option, I am unsure of what the other options are doing and I cannot find documentation discussing these options. What I can find with avaliable resources refers to the documentation of ipop but such documentation is not provided.
