Examples

data( "Kmenta" )
demand <- consump ~ price + income
supply <- consump ~ price + farmPrice + trend
labels <- list( "demand", "supply" )
system <- list( demand, supply )

## perform OLS on each of the equations in the system
fitols <- systemfit( "OLS", system, labels, data = Kmenta )

## all fitted values
fitted( fitols )

## fitted values of the first equation
fitted( fitols$eq[[1]] )

## fitted values of the second equation
fitted( fitols$eq[[2]] )
