Figure 4. A: Log-log plots of cumulative probability (P) vs. duration of inactive periods (≤20 min) for controls (A). The straight line represents the linear regression line, using the least squares method. B: Log-log plots of cumulative probability (P) vs. duration of inactive periods (≤20 min) for depressed patients. The straight line represents the linear regression line, using the least squares method. C: Log-log plots of cumulative probability (P) vs. duration of inactive periods (≤20 min) for schizophrenic patients. The straight line represents the linear regression line, using the least squares method.
