4 years ago The bspline method is not fully developed. And we don't have a clear understanding of its behavior yet.

Hello Prof, I got a warning messages when using methods = "bspline" in "fect" function ,is this warming fatal to the result? When I use "bspline", this warming comes out, and the result is obviously different from other results from "fe","ife" and "mc" methods. But I could not understand what this warming is:
Warning messages: 1: In if (class(x) != arg.class) stop(ERR.GEN.arg.invalid(arg.name, : the condition has length > 1 and only the first element will be used
This is from the codes as follow:
out.splines <- fect(Y ~ D + X, data = Data, index = c("id","time"), force = "two-way", method = "bspline", CV = TRUE, se = TRUE, nboots = 20, parallel = TRUE,cores = 8)
I would be grateful if you could give me a hand....
Best Regard, Jiajing
