Chernoff's faces

Hi!

I'm trying to test a visualization technique called Chernoff Faces using Survo MM v 3.57 on Windows 7, but i can't  follow the steps in Survo demo for Chernoff's faces because i am getting an error. After i run the first command, PLOT FOSSILS / TYPE=FACES, it tells me that it can't find the FOSSILS.SVO file, which is required for the method to work. I've also looked in the directory where the application was installed and i couldn't find any file with that name.
If i don't have the data set, the FOSSILS.SVO file, i can't test the method and i really need to do that.
It's urgent!

Thanks!

Hi Diana!

The data set is included in the same edit field as the demo (not as a file, but edit field data). If you want to copy the data to a file, you can use the command FILE COPY.

To do that separately, paste the following text to the edit field and activate the line that has a command FILE COPY. After that there should be a file FOSSILS.SVO in your current directory.

FILE COPY FOS TO FOSSILS

Hopefully this helps!

Thanks a lot!

It worked like a charm.
Now i can finally test this method.

Thanks for the fast reply!

Dear Diana,
It would be nice to see your achievements with the Chernoff's faces!

Survo is one of the earliest platforms where this "funny" technique was implemented, see

Mustonen, S. (1980). On Interactive Statistical Data Processing. 8th Nordic Conference on Mathematical Statistics, May 1980, Mariehamn, Åland. (10+9 pp.)

Please post something here (as soon as convenient for you).
We are happy to comment and help you further.

Best regards,

Hey!

I will try to post other things  during my work with Chernoff's faces.

If i encounter any difficulties i'll let you  know.

Thanks for the help!

Hi!

I have a little problem with the result of the GPLOT command for my faces. Although i have more than ten variables it keeps showing me only the first ten of them. So i am getting ten faces instead of fifteen.
This is the command i am running GPLOT FOS / TYPE=FACES without the parameter list.
Is there any limitation regarding the number of faces that it can display at a time.
I am using the data that Reijo Sund sent to me.

Try plotting with the command (i.e. add the specification FSIZE=120):

GPLOT FOS / TYPE=FACES FSIZE=120

You can see other options from the help system by activating the line:

CHERNOFF?

Thanks!

It worked.

I also had a look over the options for Chernoff's faces.
