Estimation by OLS

[yossi_shvimer_gmail_com]

Hello,
I'm new user.
I have a function with 4 coefficients, which I want to estimate with OLS:

I have the explenatory variable R(m) , and the time series (m=1,2….12)

I want to estimate the equation by OLS.
The equiation that I want to measure is:
R(m)=b(0)+b(1)*((1-exp(-m/r))/(m/r))+b(2)*(((1-exp(-m/r))/(m/r))-exp(-m/r))
The coefficients are: b(0), b(1), b(2), r.
the R(m) is the monthly yield.

Thanks 🙂
