I know that taking log can’t apply with “0” (zero); however the raw data has some of “0”.
So my question is how can I take log with such data (include some “0”? Or if you have any suggestion please let me know. My friend told me that I might classify data in group, but I have no idea how to do it. Please help.

The data is “panel data”

Thank you.

What do you want the log of zero to be?

Thank you for you response.
For your question, I still have no idea what could "log of zero" be? Actually, I don't understand EView Program very well.

Let me explain it
I do "Simultaneous Equations" between demand and supply by running data in 3 steps as follows:

1. run all data by regression
2. adjust result/equation by take log, which is the problem because "0" in data
3. estimate data by 2SLS (two-state least square)

I already test data in Stata which the program exclude "0" automaticly and has some summary. Anyway I would like to run data agian by EViews program to compare the results, but I stuck in 2nd step.



Thank you

Not sure what you mean. EViews will drop the zero observations if you're taking logs.

I'll check data now. thank you
