I am facing some issues with this model fit that I am trying to fit using nonlienar fit.

the equations are the following:

{{571, 1, 75}, {338, 2, 36}, {173, 3, 12}, {93, 4, 4}, {41, 5, 2}, {21, 6, 0}, {10, 7, 0}, {6, 8, 0}, {4, 9, 0}};

equations: (x2*phi*p*(1-p)^(x1-1))/(1-phi+phi*(1-p)^(x1-1_

parameters are phi and p

variales are {x2,x1}

When I run this I get an error that the iteration finds 0 in the denominator

Any clue on how I can resolve?
