The basic command function is stt.txt to be run in AMPL It prints text files of its Chebyshev weights, interpolation nodes and simulations of output The basic solvers are in in sttom, which solves the agents problem when there is uncertainty. To set the compact space which is relevant to the problem, we solve a basic Solow growth model in kmax.mod and then the capital stock will be within this domain. st.dat has relevant parameter values.
