Hello everybody,
I want to use 'nlsur' to estimate a system of equation of this type:
(d.var1= {a0} + {b1}*d.var2+{b2}*(d.log(var3+{a1}*(var4)^{a2})) + {ecm}*(l.var5-{a3}+{a4}*log(l.var6+{a1}*(var7)^{a2})))
(d.var8= {a0} + {b1}*d.var2+{b2}*(d.log(var3+{a1}*(var4)^{a2})) + {ecm}*(l.var5-{a3}+{a4}*log(l.var6+{a1}*(var7)^{a2})))
etc.
However, stata does not accept the operator 'd.' used in the expression d.log(var3+{a1}*(var4)^{a2}).
Is there any way to circumvent this problem?
All the best,
Ignazio
