Solving Systems of Non-linear equations
I am trying to write a function that will solve a simple system of
nonlinear equations for the parameters that describe the beta
distribution (a,b) given the mean and variance.
mean = a/(a+b)
variance = (a*b)/(((a+b)^2) * (a+b+1))
Any help as to where to start would be welcome.
