IDI fluctuation, probability density and PP plots.

<p>(a)-(c) for the experiment with pump parameter <i>p</i> = <i>I</i>/<i>I</i>_<i>th</i> = 1.0145 and threshold -1.5, (d)-(e) for the LK model simulation with pump parameter <i>μ</i> = 1.020 and threshold -1.0. In the density plots, the red curve is the fitted non-Gaussian stable density, the blue curve is the Gaussian density with the sample mean and variance, and the dotted curve is the smoothed data density. In the PP plots, a 45-degree red line is also drawn for reference.</p

Fitted stable-parameters.

<p><i>α</i> and <i>γ</i>, versus the pump parameter for two thresholds: (a), (b) experimental data; (c), (d) simulated data. For the experimental data, the maximum values of the 95% confidence interval half-widths are quite small, 0.007 and 0.003 for <i>α</i> and <i>γ</i>, respectively. For the simulated data, the maximum half-widths are also quite small, 0.01 and 0.004, respectively, and therefore the error bars (parameter +/− confidence interval) are also not plotted because they are all too small to be seen.</p
