Korotkov’s images, gender and age dependence

In several papers was demonstrated that there are significant statistical difference in GDV parameters between genders. As a whole energy parameters for women are higher compared with men. This may be illustrated by the graphs from [Polushin et al, 2009].

Fig. Gender difference in GDV parameters [Polushin et al, 2009].

In a group of people statistical distribution of the GDV parameters without filter follows log-normal distribution, typical for biological subjects. In a group of middle-aged apparently healthy people (31-52 years old) distribution has a tail in lower values, while in a group of yang people (18-21 yers old) the tail goes to the higher values. That means that in middle-aged group there are some people with very low energy, while in a yang group there are several people with very high energy.

Statistical distribution of the GDV Area with filter is more close to normal distribution.

Detailed discussion of age and gender difference for the whole setof EPIindexesispresentedinthepaper[Ciesielska-Wrobeletal2010] based on the study of population of 126 persons (81 men and 45 women).

From this we have to conclude that in quantitative analysis data for women and men as well as for different age groups should be evaluated differently.

We can investigate 3 types of Korotkov’s images depend by age:

Children (3-12 years old), Teenagers
Adult people
Gerontologic group
