Which three estimate the same equation and what is it? Which one does not work and why? What does the remaining program/command do?
a)
series dy = y – y(-1)
equation eq_y.ls dy c ar(1) ma(1)
b)
equation eq_y.ls d(y) d(y(1)) c ma(1)
c)
series dy = d(y)
equation eq_y.ls d(y) c dy(-1) ma(1)
d)
equation eq_y.ls d(y) ar(1) c ma(1)
the order shouldn’t be d(y) ar(1) c ma(1)
e)
equation eq_y.ls d(y) ar(1) d(y(-1)) c
and What do these programs do?
a) Program 1
scalar x = 0
for (!n= 1 to 100)
x = x + !n
next
b) Program 2
series y_sum = na
for !i = 0 to 40
smpl 1995Q1 1995Q1 + !i
scalar y_sum_t = @sum(y)
smpl 1995Q1+ !i 1995Q1 + !i
y_sum = y_sum_t
