Not sure if this is a bug or my own ignorance, but I've noticed that the ordering of columns in the data seem to matter. Example:
library(nowcasting) data(NYFED) base <- NYFED$base blocks <- NYFED$blocks$blocks trans <- NYFED$legend$Transformation frequency <- NYFED$legend$Frequency #randomly generated reordering shuffle <- c(7, 11, 24, 21, 10, 15, 2,1, 22, 25, 19, 5, 18, 17, 4, 12, 16, 6, 14, 23, 8, 9, 3, 13, 20) base_shuffle <- base[,shuffle] frequency_shuffle <- frequency[shuffle] blocks_shuffle <- blocks[shuffle,] trans_shuffle <- trans[shuffle] x <- Bpanel(base = base, trans = trans, NA.replace = F, na.prop = 1) x_shuffle <- Bpanel(base = base_shuffle, trans = trans_shuffle, NA.replace = F, na.prop = 1) nowEM <- nowcast(formula = GDPC1 ~ ., data = x, r = 1, p = 1, method = "EM", blocks = blocks, frequency = frequency) nowEM_shuffle <- nowcast(formula = GDPC1 ~ ., data = x_shuffle, r = 1, p = 1, method = "EM", blocks = blocks_shuffle, frequency = frequency_shuffle)
You can verify that nowEM$yfcst and nowEM_shuffle$yfcst are different. Why is this? Do you have any recommendations for a "correct" column order?
nowEM$yfcst
nowEM_shuffle$yfcst
