Table 1. Nonparametric test and test of stationarity for mean altitude and mean annual air temperature with regard to TBE, Slovakia, 1980–2004*.

Data	Test values
	RS	p value†		KPSS	p value†
Mean annual air temperature	0.55	0.01		0.56	<0.05
Mean TBE altitude	0.87	<0.001		0.86	<0.01

*TBE, tick-borne encephalitis; Rs, Spearman rank correlation test, a nonparametric test; KPSS, Kwiatkowski-Phillips-Schmidt-Shin test, a test of stationarity (no change with time).
†Probability of adopting the null hypothesis of randomness (Spearman R_S) and stationarity (KPSS).
