Hello

I am working on estimating a threshold relationship using the following program

scalar thold
scalar test
scalar i
scalar g
scalar numobs
scalar numth
series dum_thold
series resumsq_loan


numobs = 56
numth =394

for g =0.1 to numth step 0.1
dum_thold = 0
thold = grid(g)

for i=1 to numobs
test = inf(i)
if test > thold then
dum_thold(i) = 1
endif
next

equation thr_reg_loan.ls loan dum_thold*(1/inf-1/thold) (1-dum_thold)*(1/inf-1/thold) do fs trend

resumsq_loan(g) = @ssr
next


if I run it, I get the following result:

0 is not a valid index for vector-series-coefficient RESUMSQ_LOAN(g)@SSR

So the program doesn't run.

However if I put the initial value of g=1, than it works.

But I want to use loop for values from 0.1-394, step 0.1

Does anyone have a suggestion on this.

Thank you

It isn't very clear what you're trying to do with this line: If g is not an integer, what does this line mean?

this means that I want to save the value of equation residual for each g (from 0.1 to 39.4)

You'll need to create a variable that keeps track of how many iterations of the loop you've done, and use that is your index variable rather than G.

Perhaps a faster method is to use 1 to 3940 as your loop and divide everything by 10 whenever you need 0.1 to 394?

this should work. thank you for your replies
