Estimation equation in a string

[lukevancleve]

Hi,

Is there an easy way to get the estimation equation as a string? say I have an equation object that when you view it has

Estimation Equation
=======================
A = C(1)B + C(2)B(-1)


Is there a

string my_eq = ?

... to get "A = C(1)B + C(2)B(-1)"

Thanks,

Luke

Do you want the actual values of the coefficients?

I do not.

Unfortunately there isn't an easy way.

equation.@subst returns it with substituted coefficients (i.e. their values).


You can either freeze the representations view into a text object and pull off the line containing the expression you want:

Code: Select all

freeze(temp) equation.representations temp.svector temp2 %exp = temp2(7)

That might be tricky, because it might not always be the 7th row of the svector.

Or you could build up the expression yourself, getting the names of the variables and the coefficients from equation.@varlist and equation.@coeflist
