Dear All:
I try to compare with the densities of two different networks. The result come as followings:
->dsp densitydiff(Network1Rows Netork2Rows undir)
Bootstrap SE1 = 0.1354
Bootstrap SE2 = 0.2363
T-statistic? ?= 1.3690
Cohen's d? ? ?= 1.9163
Test for equal degree centralization. 20000 iterations. Data are undirected.
? ? ? ? ? ? ? ? ? ?1?
? ? ? ? ? ? ? ?Measure?
? ? ? ? ? ? ? ?-----?
? ? 1? ?Network1 ROWS 0.506?
? ? 2? ?Network2 ROWS 0.875?
? ? 3 Obs Diff 0.369?
? ? 4? p-value 0.090?
4 rows, 1 columns, 1 levels.
I have two questions about the result.
First, the title of the result "Test for equal degree centralization.20000 iterations. Data are undirected." makes me a little confuse because I am testing the difference of density not the centralization. Why the title shows the test for equal degree centralization?
Secondly, it looks like that there is no significant difference between the two networks in terms of density.
My problem is the number of density calculated by UCINET is different from the number by hand calculation.
According to the result, the density of the? Network2 is 0.875. However, my hand calculation is only 0.0708. I don't understand what the problem come from. Can any one help me solve this confused problem.? Thanks a lot!
