X-To:         STAT-L@vm1.mcgill.ca

Regarding McPherson's query about testing fit with ungrouped data, it
is more fruitful in general to test specific alternative hypotheses
by embedding the model in a more complex model, i.e. test additivity
by testing interactions, etc.  I don't know if this applies to the
problem at hand, but unlike omnibus informal tests based on the
deviance, these specific tests give rise to chi-square distributions,
reasonable power, and identifiable model corrections.

Organization: University of Virginia

Folks,
    Got a problem I've been kicking around for some time without 
satisfactory resolution.  I've got a user who does complex doubly multi-
variate repeated measures designs, along the order of 3 or 4 within 
Subject factors and 3 or 4 between Subject factors.  Usually most of 
these factors have only 2 levels, a few have 3 or more levels.  In
addition, she sometimes has covariates!

     She had been using a Fortran program on our now retired
CDC called UNENAN.  This program was NOT portable to any other system
because it was specially written to take advantage of the CDC architecture.

     This program used the "old-style" data setup where each "measurement"
or "time-period" was a case.  Because of this, it was a simple matter for
this researcher to get all of the possible combinations of within subject
and between group means.

     When we retired our CDC last fall, we converted her to SPSS, version
4.1, on an IBM mainframe running XA/CMS.

    PROBLEM:  I have been unable to get for her, all the possible combinations
of means for all permutations of between group and within subject
factors.  We have re-configured the data to use SPSS MANOVA repeated
measures procedures (the WSFACTOR/WSDESIGN).  I've spoken with David
Nichols at SPSS, Inc., and he provided a partial solution using the
transformation matrix and the MATRIX procedure, but the user was NOT
pleased with all the steps involved, and it doesn't get us all the
possible means without a fair amount of additional work.

  SAS had basically the same thing...compute lots of new variables that are
the right combinations for the means of interest and use PROC MEANS.

  Here's an example SPSS MANOVA setup:

MANOVA SCONV1 SCONV2 SCONV3 SCONV4 SCONV5 SCONV6 SCONV7 SCONV8
     BY SEX1 (1,2), POL1 (1,3), FAVOWN1 (1,2) WITH PREL1 PREL2
     PREL3 PREL4 PREL5 PREL6 PREL7 PREL8
       /WSFACTORS = LDPTG(2), NSSP (2), ldasp(2)
       /WSDESIGN= LDPTG, NSSP, ldasp, lDASP BY LDPTG, LDASP BY NSSP,
                 LDPTG BY NSSP, LDASP BY LDPTG BY NSSP
       /PRINT  TRANSFORM

   What do other folks using repeated measures designs do to generate
the between group and within subject factor means?  I'm near the end of my
rope on this one and the end of the rope looks like a noose the user
will use to string me up.

   Thanks in advance for any suggestions or solutions!

The first value (NewAverage) is of the form "average in raw score form
plus a standardized (z-) score."  This does not make too much sense to me,
unless I am missing something here.

The second value (NewVariance) also doesn't seem right to me, either.  It
is of the form "variance in raw score form plus the size of the
current squared deviation from the mean relative to the old variance."

Sounds like you are mixing apples and penquins to me!

It seems to me a better estimate for the average and variance (assuming
you know the number of elements that made up the original sample) would be:

NewN = OldN + 1

NewAverage = (OldSum + NewValue) / NewN
           = (OldAverage*OldN + NewValue) / NewN

NewVariance = (OldSS + NewSquaredDeviation) / NewN
            = (OldVariance*OldN + (NewValue - NewAverage)^2) / NewN

This, of course does assume that you know the OldN, the original sample
size....  If you don't know the original sample size, I would think you are
"up the creek without a paddle!"

About all you can do, Todd, is discard those responses for those subjects,
since you cannot determine why they wrote in a "6".  Depending on how you
plan to use the questions from the other part of the survey, you will not
necessarily have to discard _all_ of the data for those subjects.

Possibly dumb question time again...

It is well known that the proportion of successes in n trials of a binomial
experiment (each with prob[success]=p) has mean p, and variance p(1-p)/n.
What is the pdf/cdf of this quantity?  Just looking at it, it has to be the
case that the pdf converges to a spike on p as n -> big...

I am interested in the probability that the proportion of successes exceeds
some constant.  Hogg and Craig has been only so helpful, and so onto STAT-L,
and off to the library for Johnson and Kotz...

Many thanks.  -- Simon Jackman.

Subject:      Dell computers summary

date sent:  11-APR-1992 14:02:32


Greetings ...
I recently enquired about Dell computers and as a result I have received
a number of responses all infavour of Dell. For the sake of saving band width
I am not going to post them here, and as I mentioned earlier all responses were
positive.
However, FYI, I am going to post my experience with Dell.

I've bought 10 333P/33 (386) and 1 486P/33 (486) PCs from Dell Canada.

Delivery was faster than I thought, 3 days.
All token ring cards were installed, Dell installs all purchased software
and hardware for you.
Technical people were great, very friendly and knowledgeable, a **** service.

My concerns:
Sales rep seemed to be very busy, I had to call her many times and leave
messages each time I wanted to talk to her, but whenever I got hold of her she
faxed me all I'd wanted promptly.

Two of the token ring cards were faulty and were replaced next day by FEDEX.
I had to exchange an english keyboard with a bilingual one, done next day,
note, their bilingual keyboards are not Dell products and not as robust.
Generally, keyboard connection is not very robust.

All parcels were sent back to Dell by FEDEX pre-paid by Dell.

333P/386 PCs seem to be just fine, but 486P/33 PC seems to have some innate
problems: At POST 5 1/4 inch drive makes horrible noise, HD (230MB) is very
noisy and creates statics-like noise at regular intervals. Dell's Ultrascan
SVGA monitor has to be fine tuned using a special software that comes with it
otherwise screen shrinks momentarily when switching between graphics and text
screen. Tech support people said nothing they could do about the noise since
this is the way that type of HD operates.


My wish:
I'd like to see Dell include DOS and Windows and packages like this as part
of its standard deals like many other vendors do.

I am generally happy with the product but I think I should wait and see.
If everything works well I may go for the second purchae this summer.
I must say the price we paid was very reasonable (educational discount).
I've heard that Dell has just reduced the base price of their units and
unfortunately reduced their educational discount as well.

Cheers,

At the Library of Congress, they told me that, although they permit the use of

X-To:         CDROMLAN@idbsu.idbsu.edu

	During recent discussions about maximizing drive numbers with SCSI
EXPRESS, several folks mention motherboards with 12 rather than the traditional
8 expansion slots.  I haven't seen one of those around for several years.

	If the standard rules for NOVELL memory requirements hold for mounting
volumes, a 56 CD Drive SCSI-Express System could require up to (.023 x volume
size (in MB) / Block Size (default is 4)).  If each CD averages 530 MB of files
(for round numbers i.e. Novell requirement of 3 MB each), the system would
require 168MB of memory for the CD's, plus 2 MB for the operating system and
teh Server's hard drive...

	So, is there a Motherboard that (a) has 12 expansion slots and (b)
provisions for copius ammount of memory on the motherboard?  Furthermore, is
there a chasis/case that support such a motherboard (all 12 slots accessible
from hte back...)?  If so, which vendors carry them?

We're thinking about developing something along these same lines.  Currently
we have about 25 databases and many more coming online in the next 6-8 months.
The staff involvement in scheduling has been complex.  I am not aware of
any existing commercial products that would incorporate all of the variables
we would need to address...so we looking toward in-house development.  If
we get something going, I'll post to the list, but I don't expect to begin
this until sometime this summer at the earliest.

labor costs in India, he believes he will be able to offer data entry services
at very attractive rates to US customers. He would like to know where to start.
How big and how saturated is the market? Which companies in the US are likely
to be potentially interested in his services? What kind of special equipment
will he need? Is there any other way of more profitably utilizing his PC's?

   I would appreciate any help that readers may be able to provide. Kindly
e-mail your replies to me (arvind@nac.enet.dec.com), as I am not a frequent
reader of this group.

  Thank you.

	Arvind.
