Hello R users,
I am trying to estimate the parameters of a bimodal normal distribution using
moments matching, so I have to solve a non-linear system of equations. How can
I solve the following simple example?
x^2 - y^2 = 6
x – y = 3
I heard about nlsystemfit, but I don’t know how to run it exactly. I have tried
the following code, but it doesn’t really work:
f1 <-y~ x[1]^2-x[2]^2-6
f2 <-z~ x[1]-x[2]-3
f <- list(f1=0,f2=0)
nlsystemfit("OLS",f,startvals=c(0,0))
Thank You in advance for your help.
