Exposure to HAP and the Regional Pattern of Air-Related Morbidity in India: A Multivariate Analysis

Table 2

Descriptive statistics (all India).

(a) General morbidity

Descriptive statistics	MPCE	VULN	EAI
Mean	917.2	1.217	56.64
Median	757.1	1.00	66.67
Standard deviation	685.9	0.29	34.35
Pseudo SD	416.2	0.44	37.06
Sample size	132369	132369	132369
Required transformation	Square root	Takes certain values, no transformation	No transformation

A pseudo standard deviation is IQR/1.35 that should be equal to the actual standard deviation for normal density.

Median	833.33	1.00	5.00	8.00	50
Standard deviation	833.73	14.89	1.65	98.71	36.75
Pseudo-SD	503	18.53	2.22	92.66	61.77
Sample size	9556	9556	9556	9556	9556
Required transformation	Square root	Takes certain values, no transformation	Takes certain values, no transformation	1/square	No transformation
