Analysis of the Transmissibility Change of 2019-Novel Coronavirus Pneumonia and Its Potential Factors in China from 2019 to 2020

Table 2

The correlation coefficients of the three BDIs.

Pearson’s correlation coefficients; Spearman’s rank correlation coefficients	BDI of “novel coronavirus”	BDI of “coronavirus”	BDI of “coronavirus pneumonia”
BDI of “novel coronavirus”	1	0.875 ()	0.84 ()
		0.847 ()	0.785 ()
BDI of “coronavirus”	0.875 ()	1	0.96 ()
	0.847 ()		0.965 ()
BDI of “coronavirus pneumonia”	0.84 ()	0.96 ()	1
	0.785 ()	0.965 ()

Correlation is significant at the 0.01 level (2-tailed). The first line of the result is Pearson’s correlation coefficients and value, and the second line is Spearman’s rank correlation coefficients and value.
