Hybrid model issue

[Nyc_prop]

Hello,

I have a model like this,

LnY=b1 ln (x1) + b2 ln (x2) + ln ( a1z1+ a2z2) + e.

Which procedure can solve this kind of a model which has an additive part as well as a multiplicative part. Also, will that procedure address the global min and max solutions properly? Kindly advice.

You may want to describe the questions you want to answer from your data as there may be a choice of procedures that will use your specific model but not all provide the same analysis.
