Error messages/systemfit package
Hello !
I’m trying to estimate a system of equation (demand and supply) using the systemfit package. My program is:
library(systemfit)
demand <- tsyud ~ tsyud1 + tsucp + tspo + tssn
supply <- tscn ~ tsyn + tsqn + tsksn + tsucp
system <- list(demand=eqdemand, learning = eqsupply)
labels <- list(demand="eqdemand", learning="eqsupply")
inst <- ~ tsupp1 + tsupp2 +
tsupp3 + tsyus1 + tsupf + tsd1 + tsyud1 + tspo + tssn + tsupp + tsus +
tsus1 + tsyn + tsqn + tsksn
