Hello SPSSForum,

I recently started to work frequently with SPSS and so far I got well around just with searching the internet for solutions. But now I am at a problem where I don't even now how to google it. Therefore I am mainly asking for hints where I can find material how to teach myself. However here is the problem description where I got stuck.

I have a big Database with the following variables:

- Country_i -> Domestic country

- Country_j -> Destination country

- Psy_Dist_1 ->Psychic Distance 1st Dimension

- Psy_Dist_2 ->Psychic Distance 2nd Dimension

- Psy_Dist_3 ->Psychic Distance 3rd Dimension

- Psy_Dist_4 ->Psychic Distance 4th Dimension

- Psy_Dist_5 ->Psychic Distance 5th Dimension

From the five dimensions of Psychic Distance I have to calculate now one composite index with the formular

|k=1 to 5| sum (( Psy_Dist_ijk)^2 /V_ik /5)

where

i is the fist country

j the second country

k the kth dimension of psychic distance.

V_ik is the variance for the Psychic distance of the kth dimension and th ith country across all j countries

Especially including the calculation of V_jk is something I don't know how to start.

Some hints for tutorials or anything like that would be awesome

Thank you in advance and best regards

Marcus
