Hello to whomever can help
I have a data set like following:
I tried the following program, but it give me error.
PROC IML;
print (mu_vec['MSFT']);
error message is like following. Please help. Thank you.
If you are using a column name attribute, you need to specify the name as a column:
mu_vec[, 'MSFT'];
For more information and examples, see "Access rows or columns of a matrix by names."
First you have to read the data from the data set into a matrix or vector.
Read the article "Reading ALL variables INTO a matrix."
Is the data in a data set that has one observation and three variables? If so, then the PROC IML statements look like this:
proc iml;
use Have;
read all var {"MSFT" "NORD" "SBUX"} into mu_vec;
close Have;
If you want to read all of the numeric variables, you can use this:
read all var _NUM_ into mu_vec[colname=varNames];
If you are using a column name attribute, you need to specify the name as a column:
mu_vec[, 'MSFT'];
For more information and examples, see "Access rows or columns of a matrix by names."
