Summary(model) runs pretty slow #79

Open jhan0317 opened 2 years ago

jhan0317 commented 2 years ago

Hello, the summary function runs quite slow if I do:

model <- synthdid_estimate(setup$Y, setup$N0, setup$T0) summary(model)

It can be slow.  One of the things it reports is a bootstrap standard error, which takes some computation.

If you call summary(model, fast=TRUE), it should be much faster, but it'll report a jackknife standard error that can be a bit less accurate.  See the documentation for vcov.synthdid_estimate for more on these standard error estimates. On Feb 7, 2022, 11:35 PM -0500, J Han @.***>, wrote:
