Take a look at the proc freq documentation. One thing you will find is:
Beginning in Release 6.10, use the AGREE option in Base SAS PROC FREQ.
Before Release 6.10, create a three-way table with a stratum variable
identifying each subject (or matched group), a variable indicating each
occasion (condition or individual within matched group), and a binary
response variable. Then use the CMH option. For example, if each subject
gives a binary response to each of two drugs, use the statement:
tables subject*drug*response/cmh2 noprint;

Suppose I take samples at once per minute for a data logger. Do I
still need an anti-aliasing filter? The sampling freq would be 1/T
where T=60 secs...so how is this possible? The values of the
capacitors etc would be hugh. Of course I could over-sample1000s of
times...is this the norm?

I'd like to get some inputs on how to solve a sampling requirement at my
end. I have two datasets - Dataset A (6M records) and Dataset B(50K
records). Both datasets have a common ID/ Strata (ex: B100101,B110101,
etc). Please note that there are more than 500 unique IDs. I'd like to use
the distribution in Dataset B to extract 50K records from DatasetA. Any
help would be much appreciated.
Sounds like the general process is:
a) use PROC FREQ (or similar) to generate a frequency dataset from DATASET B
for your distribution; something like

The grid applied to an image is saved with the image (if saved as XCF of

Hi, I have a general question of this newsgroup if I may. I have a
non-commercial website detailing a certain vintage video tape
recorder. I have an idea for the site, which is to have a "Virtual"
version of the machine. I have a good image of the TV/vcr that I want
to use, the idea being that the surfer to my page would be able to
click on one of the buttons on the TV whereas the Java program would
play one of a few random MPEG video clips taken straight from the
original media. The video would be displayed in the screen portion of
the digital image of the TV.

Could anyone explain why an array will always be faster than a hash object
described in SAS Prog3 course note??
Not sure if I agree it is always faster. Depends on what problem you
are actually trying to solve.
In terms of physically accessing the memory location an array is
stored in a nice evenly spaced block of memory.
So if your program asks for item number 10 SAS knows immediately where
to find it.
Hashes are stored in some type of binary tree. So when you ask for
item 10 SAS needs to make one or more refences to the index (is that
the right term) for the hash to figure out where it is l...2 Questions #2

important than the other. In other words, you may have a variable Income
