Hi, community,

 

I'm running SAS 9.3 on 32 bit-System.

I have the following interaction plot - thrown out by

 

ods graphics on;
TITLE2 'paarweise Differenzierung der Höhenmittel 2015'; TITLE3 'Model Höhe = Herkunft Wiederholung (&Interaktion) / ss3';
PROC GLM DATA=beta;
    BY VFL; CLASS hk wdh;
    model mh=hk wdh /ss3;
    lsmeans hk / adjust=tukey pdiff=all;
    RUN; QUIT;
ODS graphics off;

 

Part of the Output, while the model is significant, is the attached graphic (in the html-output).

 

My research for the meaning of the dots and circles are resultless yet. Is there someone, who can tell?

The data set has three values for each class of hk.

 

Thx to helpful readers!

The circle, cross and x are a scatter plot of the original values you supplied. Each symbol represents one level of the variable WDH.

The solid line graph represents the modeled value of the circle, or first level of WDH.

The simple dashed line is associated with cross and the second level of WDH.

The long-short dashed line is associated wth X and third level of WDH.
