Hello,
I am a beginner in Econ. I would like to test the effect of some
factors on the production of specific output using the Cobb-Douglass
production function. I would like to know if you have any concerns
about the results.
Y represents output, x1 labor, x2 fertilizer, x3 land, x4 seed and x5
is capital. I wonder why the x1 coefficient is negative for example.

I tested for heteroskedasticity and auto-correlation but nothing changes.
Thank you.
