Standard deviation in factoriel desighn

vnazery_yahoo_com — Mon, 05 Jan 2015 18:22:53 GMT

Hi There

how can I find SD in factorial experiment design . A, B, C ,D and E are factors and rep. is three replicate . data1, 2, 3 are measurements for example. what is the code for getting standard deviation in A*B, A*B*C, or C*D or etc.?

A simple standard deviation within combinations of the variables A through E can be accomplished with Proc Means or Summary;

proc means data=have stddev;

class A B C D E;

var data1 data2 data3 ;

run;

The columns A through E with 1 in the value are the variable combination used for the calculation

proc summary data=have;

class A B C D E;

Var data1 data2 data3;

output out=want stddev=;

run;

which I usually find it a tad easier to read the output dataset than the way MEANS prints the data.

We don't normally speak of the standard deviation of the raw data within certain groupings with respect to a factorial design.

Normally we speak of the standard deviation of the parameter estimates, or of the residuals. Is that what you want?
