Exponential time series analysis has been an integral part of lattice
quantum field theory calculations for three decades. Until recently, the
level of sophistication has been relatively modest since the number of computable
time samples was limited by available computational resources to at
most a few dozen times, enabling the reliable estimation of only a few exponentials.
Recent algorithmic advances, coupled with continued growth in high
performance computing following Moore’s Law, has enabled calculations of exponential
time series with a hundred or more time samples and generated new
interest in finding reliable analysis methods for estimating many exponentials.
We review the methods currently used to analyze lattice quantum field theory
