I've scanned the SAS/IML® 13.2 User’s Guide (UG) and didn't find a list of of functions that operate on the columns of an NxM array, returning a 1XM vector of results.

So I made this list: CV KURTOSIS MEAN MEDIAN SKEWNESS STANDARD VAR

Did I miss any? Is this list somewhere in the UG?

Rick is absolutely right. But there are already some IML version of these function . Like :

x = {1 0,

2 1,

4 2,

8 3,

16 . };

kurt = kurtosis(x);

print kurt;

x = {5 1 10,

6 2 3,

6 8 5,

6 7 9,

7 2 13};

mean = mean(x);

print mean;

x = {1 3,

2 3,

4 9,

10 0};

med = median(x);

print med;

They are all column operation .

I assume you are primarily interested in descriptive statistics for each column. You can add the following functions:

COUNTMISS

COUNTN

COUNTUNIQUE

MAD

QNTL

QUARTILE

Also, subscript reduction operators enable you to perform columnwise operations:

SUM via x[+, ];

PROD via x[#, ];

MAX via x[<>, ];

MIN via x[><, ];

Index of maximum via x[<:>, ];

Index of minimum via x[>:<, ];

SSQ via x[##, ];

Rick -- thank you -- great reply -- this is exactly what I'm interested in.

BTW, I found QNTL last night going through your helpful** tip sheet**.

If I don't make a mistake, these data step function also could be applied to IML.

Check it at the bottom of IML documentation, you can find them all.
