Newly introduced pairs and combinations versus z-score. (a) and (b) show z-score of a new pair when it was firstly combined. (c)-(h) each x-axis indicates a year that the new combination was firstly used, and each y-axis represents \(z_{\mathrm{med}}\) (c)-(d), \(z_{\mathrm{min}}\) (e)-(f), and \(z_{\mathrm{med}}-z_{\mathrm{min}}\) (g)-(h). (a), (c), (e), and (g) are for classes. (b), (d), (f), and (h) are for subclasses. Shaded regions represent standard deviation.
