Table 2.
Mean () and standard deviation () of the difference between Model A and Model B minus two log likelihood function values over all simulated conditions where the convolution kernel covered 1/2 a cycle of the simulated DLO (i.e., the embedding dimension was 1/2 the number of samples per cycle). ( indicates the percent of comparisons where this difference exceeded a two degree of freedom chi-square critical value of 5.991 and Cnvrg indicates the number of times both models converged out of 1,000 replications so that the likelihood difference could be calculated)
