What does this results mean from cross distances using euclidean distance

ekotas

Hi,

My apologies if this is a really stupid question...

I've ran cross distances using Euciladean distance on 2 excel files, one containing 1 row of relevant keywords etc, 1 containing 504 rows. The aim was to compare the similarity of each row to the relevant keywords. If that makes sense. 

Ok so it all worked, which is great!! Except I don't know what the numbers mean.... can anyone shed some light on this please. Perhaps it isn't actually doing what I think it is doing??

thank you so much

Hi,

 

lets say you got two attributes age and salary. What Cross Distance is doing for each item in the reference and the request set is:

 

distance(ref_i, req_j)

 

if you use euclidian distance you get:

 

d = sqrt (   (age_i - age_j)² + (salary_i - salary_j)² )

 

i hope this helps.

 

BR,

Martin
