Dear Colleague

  I am trying to figure out how to use R to do OLS restricted VECM regression. However, there are some notation I cannot understand.

Please tell me what is 'ect',  'sd' and 'LRM.dl1  in the following practice:

#OLS retricted VECM regression
data(denmark)
sjd <- denmark[, c("LRM", "LRY", "IBO", "IDE")]
sjd.vecm<- ca.jo(sjd, ecdet = "const", type="eigen", K=2, spec="longrun",
season=4)
sjd.vecm.rls<-cajorls(sjd.vecm,r=1)
summary(sjd.vecm.rls$rlm)
sjd.vecm.rls$beta

Response LRM.d :
Call:
lm(formula = substitute(LRM.d), data = data.mat)

Residuals:
      Min        1Q    Median        3Q       Max
-0.027598 -0.012836 -0.003395  0.015523  0.056034
