I believe the author that Ellen quoted was referring to MCS and, if so, I agree
with that author. IMHO, there will eventually be MCS software that will allow
high school students to run circles around what today's PhDs do with closed form
solutions.

As one of the 'data mining
"Data Mining" is a loosely and vaguely defined term that refers to things that
people do to understand and explore data. It means different things when used
by different people. It may mean one of the following:

Thanks, Ellen. Evocative quote, isn't it? It's that "without requiring
*any* (!) specialized knowledge" that will be the dangerous part, if read
too literally by the naive.

I'd like to make a somewhat related point. There are many educational
tools that I've found have a great effect on non-statisticians. One if these
is to take one of their datasets, randomly permute the column of Y-values,

I think, now is the time when we have to decide "Do we accept DATA MINING as
a part of statistics or do we keep neglecting this field as before".
I am sure there would be few statistics students like me who feel that Data
Mining is very much
I have been following the discussion on Data Mining blooper for a while.
Being a first year graduate student in statistics, my comments on this issue
might sound premature. Nevertheless, I would put forward my observations.
What I have learnt so far from my interaction with the statisticians

They are amazingly misleading. A basic stat book will explain why. One example
is the statement that traditional statistical methods assume that predictor
variables
are uncorrelated with each other - incredible!

Can you be more specific on what the misleading statements are? And why you
think they are misleading.

While hunting for URLs for KDCentral.com, I encountered several
misleading statements about Statistics made by Data Mining people.
I've posted 3 of them to my bulletin board. If you encounter other
wrong remarks, I invite you to post them to the board too at
