The first box lets you specify a number of lags while the second box specify the group of informational time series variables (𝑋𝑡) from which the unobservable factors 𝐹𝑡 is estimated using first k principal component. The next box specify slow-moving variables. Slow-moving variables are not assumed to respond contemporaneously to unanticipated changes in the variable which is ordered last in 𝑌𝑡. On the next box enter a group of selected macroeconomic variables for impulse response analysis. On the next box enter a vector of transformation code of Y and selected macroeconomic variables: 1=no transformation; 4=logarithm; 5=first difference of logarithm. On the next (6th) box just put names of 𝑌𝑡 and selected macroeconomic variables. It should be text object which contain columns of names. On the next box enter 𝑌𝑡 variable. It should be series, not group. Other boxes specifies some optional inputs.
