The finding that the SEP is not distinguished from the SEB regarding TTR or D, indicates that prime ministers refer to a similar diversity of political content and in a similarly balanced way in the two types of addresses.
the results indicate that the SEP has a significantly larger N than the SEB, and the two types of addresses are not distinguished by D. 9 In Figure 3, the solid line represents the mean value of ttR of the SEP, the dashed line represents the mean value of ttR of the SEB and dotted lines represent 95% confidence intervals of ttR of both types of addresses, incremented by 500 tokens constructed by Monte Carlo simulations.
