4 years ago Hi kbal has recently changed its syntax. I'm in the process of updating tjbal to keep up with kbal. Sorry about that.

Hello, When trying to replicate the example code https://yiqingxu.org/software/tjbal/tjbal_examples.R, the balancing processes give errors from the "Mean Balancing" section onwards. Only the DID example seems to work.
Here is the first error: mean balancing
out.mbal <- tjbal(roa ~ treat + so_portion + rev2007, data = npc,
-
index = c("gvkey","fyear"), kernel = FALSE, demean = FALSE,-
bootstrap = TRUE, nboots = 20)Seek balance on: roa2005, roa2006, roa2007, so_portion, rev2007
Optimization:
Error in kbal(X = data[, matchvar], D = data[, D], method = method, sigma = sigma[i], : unused arguments (X = data[, matchvar], D = data[, D], method = method, sigma = sigma[i], linkernel = (1 - kernel))
