```Date: Thu, 3 Jun 2010 08:06:26 -0400 Reply-To: Josh Sender: "SPSSX(r) Discussion" From: Josh Subject: Distance calculation and Output Hi, I hope someone can help me with this. I have information of two groups and I wish to calculate all Euclidian distances between the obs. Example: Data ID Group V1 V2 V3 1 1 98 16 90 2 1 41 49 78 3 1 26 89 47 4 2 3 71 68 5 2 52 32 94 6 2 87 57 86 So, for each combination of ID from Group 1 and ID from Group 2 I wish to calculate the Euclidean distance Distance = SQRT{ (V1(1)-V1(2))^2 + (V2(1)-V2(2))^2 + (V3(1)-V3(2))^2} The type of Output I wish to have is : ID1 (Group) ID2 (Group) Distance 1 (1) 4 (2) 67.0373 1 (1) 5 (2) 63.25346 1 (1) 6 (2) 62.68174 2 (1) 4 (2) 78.05127 2 (1) 5 (2) 63 2 (1) 6 (2) 106.4472 3 (1) 4 (2) 66.16646 3 (1) 5 (2) 59.74111 3 (1) 6 (2) 99.42334 (Column 2 and 3 -(Group) are not necessary) thanks in advance!
