Hello, I'm using test.value in "ictreg" for testing Design Effects. I got this error:

test.value.LC1.Yb1 <- ict.test(LC1$Yb, LC1$treat, J = 4, gms = TRUE) Error in t.test.default(y[treat == 1] <= j, y[treat == 0] <= (j - 1), : data are essentially constant

Would be much appreciated for further advices/suggestion to deal with the error. Kind regards, Apinya
