Ma. Samuel, ESTIMATING PERTURBATIVE COEFFICIENTS IN QUANTUM-FIELD THEORY AND STATISTICAL PHYSICS, International journal of theoretical physics, 34(7), 1995, pp. 1113-1122
We present a method for estimating perturbative coefficients in quantu
m field theory and statistical physics. We are able to obtain reliable
error bars for each estimate. The results are in excellent agreement
with known exact calculation.
