I do not understand the problem as stated. if x[i] and n[i] are known,
and unless sum(n)=0, your dataset reduces to a set of nrow(dataset)
independent linear equations with nrow(dataset) unknowns (the beta[i]),
whose solution is trivially beta[i]=log(x[i]/n[i])-log(sum(x)/sum(n),
except when n[i]=0 in which case your equation has no solution.
Could you try to re-express your problem ?
