Break up the code and check each section.

did the file import correctly? Check your input statement, there's a .1 there that seems random

data q4;

infile 'kredit.txt';

input tz 1-9 kredit 11 hight 13-15 .1;

Try specifying the dataset directly,

proc ttest data=q4 plots=all;

class kredit;

var hight;

run;

clcl,

It would help to see more.

Start with a new SAS session (your log showed line 317, so the underlying problem could have been earlier), run just that code and post the ENTIRE log.

What version of SAS are you using, because the PLOTS statement for PROC TTEST only became available in 9.2. I have 9.1.3 and am getting the same error message as you, so I suspect that is the cause.

Re: proc ttest

clcl — Tue, 17 Jul 2012 08:26:42 GMT

yes i am also running 9.1.3 , so there is no way to make the plot ??? in our version ?

Not in TTEST. I tend to use PROC UNIVARIATE to create histograms, so I guess you can create an output dataset in TTEST and then use UNIVARIATE to produce the histogram.

I don't think you need to output from proc TTest

Something like the following should give you similar results, but I have 9.3 so I might be wrong.

ods graphics on;

proc univariate data=sashelp.class noprint;

class sex;

histogram weight;

run;
