We analyse a method to determine the short-time exponent θ related to the critical initial slip in stochastic lattice models. In this method it suffices to start with an uncorrelated state with a vanishing order parameter instead of departing, as is usually done, from an initial state with a nonvanishing order parameter. The exponent θ is calculated by the time correlation of the order parameter. This method, deduced previously for up–down symmetry models, is extended here to include models with other symmetries. We also consider the extension to cover models with absorbing states.
