Dear tom mitchell,
Greetings from CARMA! We are contacting you in
your role as a CARMA Contact for your school.
We would like to remind you of the upcoming
Webcast on Friday, October 26 starting at 12:00 PM (EST) on the Relative
Importance of Predictors with Regression Models. The presenter is Dr. James
LeBreton from Purdue University. Bellow is the abstract for the class.
Abstract - The search for a
meaningful index of the relative importance of predictors in multiple regression
has been going on for over 40 years. This type of index is often desired when
the regression is being used for theory-testing or explanatory purposes.
Previous research has documented how most indexes of relative importance yield
identical results when predictors are uncorrelated. Unfortunately, in the
organizational sciences, predictors are seldom orthogonal and often are quite
correlated with one another. In the current presentation I review several
classic indexes of importance and remind viewers of their limitations. I
then review two newer and much more promising ways of estimating importance:
dominance analysis and relative weight analysis. These techniques are
compared and contrasted before closing with some suggestions for organizational
researchers.
Biography - James M. LeBreton
is an Associate Professor in the I/O Psychology program at Purdue University. He
received his Ph.D. in 2002 from the University of Tennessee. His recent research
focuses on the development and application of new statistics and research
methodologies designed to improve the decisions made by organizational
scholars. Current projects involve 1) statistical techniques for
determining the relative importance of predictors in multiple regression models,
2) the development and evaluation of statistics designed to measure interrater
agreement and reliability, and 3) statistical techniques for analyzing
longitudinal and multilevel data. He also conducts research on the relationships
between personality traits and behavior in organizations. Specifically, he
is examining how aberrant personality traits (e.g., aggression, psychopathy) are
related to behavior in organizations (e.g., test faking, counterproductive
behavior, decision making, perceptions of corporate transgressions). His
work has been published in journals such as the Journal of Applied Psychology,
Personnel Psychology, and Organizational Research Methods. He currently serves
on the editorial board of Organizational Research Methods and was awarded the
Best Reviewer of the Year Award for 2006 by that journal.
To make sure that you benefit the most from
your membership during the live session, please TEST YOUR
CONNECTION. In addition, the testing procedure is exactly the same as
the process you will go through to connect to the live session. Since this is
the first webcast of the year, it is always a good idea to practice the process
before the webcast.
Instructions for testing you
connection and for accessing the live sessions are available at
http://www.pubinfo.vcu.edu/carma/WebcastConnection.asp
. Again,
we strongly recommend that you test your connection,
even if you have used a computer as a viewing machine for RealPlayer videos
before. Sometimes, without your knowledge, alterations may have been made to the
network settings or to the machines.
Once more, the procedure for the
test is the same as the one for the live connection but for one detail.
On step 8, instead of clicking on the "Watch Live Webcast" button, you will
click on the "Test Webcast Connection" button to proceed to connect to the test
video. If you can watch the video, you are ready to go. Regarding the live
sessions,
please, initiate your connection as soon as possible. The live
signal will be available at 11:30 AM (EST).
We also would like to remind you that each
organization is responsible for updating their viewing room information in our
website before each live session. Any of the three membership contacts can
update the viewing locations. This can be done through the "Update Program
Registration" link at the CARMA Website User Area. After clicking on this link,
click the 2007-2008 CARMA Consortium Webcast Program, and you will be taken to
the "Update Registration" page. At the bottom of the page, just above the IP
address form field, you will find a field that reads "Viewing Room". Enter the
desired information in the available form field, and click on submit.
The
viewing room information is available in two pages. The first link reads
"Viewing Rooms at Current CARMA Consortium Webcast Member Organizations" and can
be found at the
CARMA Website home page. The direct
link is
http://www.pubinfo.vcu.edu/carma/ViewingRooms.asp
. The other page where this information is available is at the "
Current
CARMA Consortium Webcast Members" page.
Please, update the
viewing room information as soon as possible.
A last reminder. During the live sessions,
attendants may send us questions which, after being screened by us, will be
answered live by the presenter. Questions' senders remain anonymous. Don't wait
until the last minute to send us your questions. Please do it throughout the
lecture. Send questions to both
