False-positive rate (probability) for the statistical test of correlation in a time series characterized by computer simulations. The statistics were obtained from 10,000 simulations of independently identically distributed Gaussian random variables for X and Poisson random variables for Y. The parameters used to generate the simulated data are the same as those used to generate Fig. 2.
