我想要gmm滚动回归，然后设置下面的代码。
dogmm <- function(x) {gmm(ALLX$DE~ ALLX$SMB_L, x = ALLXbm)}
kk=rollapply(dogmm, ALLXbm,width=24, by.column = FALSE)
错误讯息是
Error in zoo(rval, index(x)[i]) :
“x” : attempt to define invalid zoo object
即使我花了很多时间，我也无法弄明白。当我单独尝试gmm代码时，它确实有效
gmm(ALLXbm$DE~ ALLXbm$SMB_L, x = ALLXbm)。我在想，问题出在rollapply代码中。对不起，这是我第一次尝试GMM。请帮帮忙？
