I want to do Discriminant Analysis by using SAS. But there is something wrong in my data set after I transfered the character data into numeric data.
At first, the dataset were character, so my first step was to tranform it into numeric data, by using following data:
【
data newalcohol;
set alcohol(rename=(Meoh=old1 Acet=old2 Bu1=old3 Mepr=old4 Acal=old5 Lnpr01=old6));
Meoh = input (old1,best5.);
Acet= input (old2,best5.);
Bu1 = input (old3,best5.);
Mepr = input (old4,best5.);
Acal = input (old5,best5.);
Lnpr01 = input (old,best5.);
drop old1 old2 old3 old4 old5 old6;
run;
】
And then, I used the following data to do the test:
【title'Discriminant Analysis of Alcohol';
title2'Using Discriminant Function';
proc discrim data = newalcohol outstat=newalcohol
wcov pcov method = normal pool = test
distance anova manova listerr crosslisterr;
class type;
var Meoh Acet Bu1 Mepr Acal Lnpr01;
run;】
However, the warnings showed up here:
【
WARNING: 77 observations in DATA= data set or BY group will not be included in the analysis due to missing values.
ERROR: At least 2 complete observations are required in DATA= data set or BY group.
NOTE: The SAS System stopped processing this step because of errors.
NOTE: There were 77 observations read from the data set WORK.NEWALCOHOL.
WARNING: The data set WORK.NEWALCOHOL may be incomplete. When this step was stopped there were 0 observations and 9 variables.
WARNING: Data set WORK.NEWALCOHOL was not replaced because this step was stopped.
】
I believe there must be something wrong within my dataset, but I didn't know how to fix it.
Can anyone help me? Thank you.
