LS Means Matrix interpreting - Multiple comparison

jonatan_velarde — Thu, 17 Sep 2015 18:02:56 GMT

Good Evening my SAS friends:

Here i am to get some help about constructing the significance difference ussing LS_MEANS means comparison matrix, weel i have an example to solve (with your help):

Here is the significance LS MEANS matrix :

i/j	1	2	3	4	5	6	7	8	9	10	11	12
1		1.0000	0.7619	0.2159	1.0000	1.0000	0.6868	0.1134	1.0000	1.0000	0.6291	0.0288
2	1.0000		0.8421	0.1318	1.0000	1.0000	0.7926	0.1631	0.9998	1.0000	0.7434	0.0442
3	0.7619	0.8421		0.0002	0.1632	0.7513	1.0000	0.9999	0.0840	0.5783	1.0000	0.9929
4	0.2159	0.1318	0.0002		0.0630	0.0037	<.0001	<.0001	0.0843	0.0053	<.0001	<.0001
5	1.0000	1.0000	0.1632	0.0630		0.9658	0.0070	<.0001	1.0000	0.9915	0.0017	<.0001
6	1.0000	1.0000	0.7513	0.0037	0.9658		0.4299	0.0058	0.8339	1.0000	0.2921	0.0002
7	0.6868	0.7926	1.0000	<.0001	0.0070	0.4299		0.9337	0.0008	0.1717	1.0000	0.5166
8	0.1134	0.1631	0.9999	<.0001	<.0001	0.0058	0.9337		<.0001	0.0006	0.9121	1.0000
9	1.0000	0.9998	0.0840	0.0843	1.0000	0.8339	0.0008	<.0001		0.9205	0.0001	<.0001
10	1.0000	1.0000	0.5783	0.0053	0.9915	1.0000	0.1717	0.0006	0.9205		0.0828	<.0001
11	0.6291	0.7434	1.0000	<.0001	0.0017	0.2921	1.0000	0.9121	0.0001	0.0828		0.4230
12	0.0288	0.0442	0.9929	<.0001	<.0001	0.0002	0.5166	1.0000	<.0001	<.0001	0.4230

Following this table, arriving to the conclussion i arrives to this result:

1 -> bcde

2 -> bcde

3 -> abcd

4 -> e

5 -> cde

6 -> bcd

7 -> ab

8 -> c

9 -> de

10 -> bcd

11 -> ab

12 -> a

Well my friends, i made this manually...and for this case i would like to know if there is any command line to get this kind of results atumatically. to obtain this type of result:

EXAMPLE

Tukey Grouping Mean N Treatment

A 192.58 9 1

B A 183.69 9 2

B A

B A 161.21 9 3

B A

B A 156.47 9 4

B A

B A 147.69 9 5

B A

B A 142.30 9 6

B A 142.30 9 7

Switch from GLM to GLIMMIX (you will need to learn some sytax), and use LINES option on the LSMEANS statement. Works great.

LSMEANS treatment / diff LINES;
