I'm new to EViews, having used Stata for 10 years, so apologies if this is a beginners question.
I am struggling with estimating the following (S curve) equation:
Y = 1/ (C1+C2 * C3 ^X)
I have a panel of 57 countries with data over 1996 to 2019 and I want to pool the data to estimate the above equation.
I read the data into EViews as dated panel, with country as crossID and year as dateID. Now when I click on new object --> estimation and specify my equation, I get the "near singular matrix" error. I checked the correlation between my independent and dependent variables and it is "just" 30%. I'm thinking that I might make a beginners mistake when estimating. Could anyone advise me? Do I need to create a pool object first? Or is it because I have some missing values?
Many thanks
