I have read some of the venn diagram e-mails recently. If we restrict the
sets to be represented by (perfect) circles only, it may happen that for
certain situations the circle-only venn diagram does not exist.
For 2 sets, the circle-version venn diagram always exists. First you draw 2
circles, w

: MANOVA is a canonical correlation problem.
The program I would choose to accomplish this is Visio. There are various
versions of this program ranging from a simple drawing package to a version
that will accomodate CAD. It is a microsoft product that has made drawing so
much easier for those of us who do not wish to struggle with CAD.

My old computer program MANOVA has a built in test of parallelism in
multivariate ANCOVA. It's really standard multivariate regression theory
although it isn't widely known. (TW Anderson gave MANOVA and CanR as two
different eigenproblems).
They are easily shown to be e

says
"the matrix X'X is greatly influenced by roundoff errors and is often
ill-conditioned ... An excellent way of solving (the LS equations) is
through an orthogonal triangular decomposition of X.

Hi: I am new to the list and have a question about bootstrap hypothesis testing. I am
testing the equality of two means according to Algorithm 16.2 in An Introduction to
the Bootstrap by Efron and Tibshirani (1993). They define the estimated ASL as
#{t(x*b) >= tobs}/B. It seems to me that this
Let me clarify my previous posting. I want to do a confirmatory factor
analysis to validate a questionnaire. There are 45 questions (subjects
answer using a 1-5 scale). Theoretically, there are 3 subscales with
15 items on each. In a CFA, that gives me 3 factors, 45 error terms,
14 factor loadin

One approach: (I assume that by "residual" you mean (O-E)/sqrt(E) for
each cell of a two-way frequency table, where O=observed frequency and
E=expected frequency under the null hypothesis). For the several (or
the single) largest residual(s), report O and E as proportions (of total
N). Expr
