Hi Listers,

 

I am trying to run a cluster analysis of 90+ records data set with 10 variables. All variables are

categorical:

1- Yes

2- No

88 - Not sure

 

I've used Hierarchical Cluster Analysis with Between-Groups Linkage method and Squared Euclidean Distance.

I got only two clusters, see below frequency results.

 

CLU9_1 Average Linkage (Between Groups)
$B!! (B		Frequency	Percent	Valid Percent	Cumulative Percent
Valid	1	5	5.4	5.8	5.8
	2	48	52.2	55.8	61.6
	3	1	1.1	1.2	62.8
	4	5	5.4	5.8	68.6
	5	2	2.2	2.3	70.9
	6	1	1.1	1.2	72.1
	7	1	1.1	1.2	73.3
	8	22	23.9	25.6	98.8
	9	1	1.1	1.2	100.0
	Total	86	93.5	100.0	$B!! (B
Missing	System	6	6.5	$B!! (B	$B!! (B
Total		92	100.0	$B!! (B	$B!! (B

 

Is there any way to increase the number of clusters?

 

Thank in advance.
