LAMBDA l CONSULTING

Lambda Consulting is a sole proprietorship consulting service provided by

Robert J. Porter, Jr. Ph.D., Professor Emeritus of Psychology, University of New Orleans

 

Welcome to the About Lambda Consulting page:

Hello, I am Bob Porter.   I have over 25 years of consulting, teaching, and research experience in psychology, statistics, and computer applications.  I retired early from my academic position to pursue personal interests, as my own boss.  You can view my Curriculum Vitae for more information about my background and qualifications.   I also have a clinical practice, if you are interested in those services, visit my Clinical Web Site..

IN CONSIDERING MY SERVICES, YOU MAY WANT TO FIRST CONSIDER MY PHILOSOPHY ABOUT STATISTICS AND DATA ANALYSIS.  

I  BELIEVE:

                    l Noise and error are just data you haven't been introduced to yet.   l

                    l Most statistical analyses obscure rather than reveal.  l

                    l Statistical consultants should find out what their clients want and design analyses to fit the questions, not the other way around.  l

                    l Most real-world systems are nonlinear.  (That's stat-talk for "Murphy's Law"!)  l

My consulting services include:

o        Design and validation of questionnaires, psychological tests, and similar instruments.

o        Complex research designs, including factorial, multivariate, and factor analytic studies.

o        Experimental designs for nonlinear (chaotic) systems research.

o        Program evaluation.

o        Qualitative and other special methods.

o        Autocorrelation, linear and nonlinear regression, spectral analysis and other time-series methods.

Traditional consulting services are available.  However, I specialize in the difficult and unexpected problems in design and data analysis which often occur in real-world settings. Examples include post hoc hypothesis testing, "proving the null hypothesis" problems, incomplete data sets, surrogate data use, resampling procedures, "violations" of parametric assumptions and "nonparametric" analyses, and "effect size" issues.   In addition, I can usually figure out what journal editors, grant reviewers, and thesis committee members want when they "suggest the researcher obtain help with statistics." I like a challenge.

I am familiar with most computer statistics packages (SPSSİ, SASİ, SPLUS, R, etc.) and have extensive experience working with computers in a number of settings.

I would be happy to provide a free email consultation and estimate of costs.   Ask about reduced-fee, or free, services for students and nonprofit organizations.

Please Email me a brief summary of your statistics questions, research design issues, or other inquiries.

Thanks for visiting!                                                                           RETURN TO HOME PAGE

Lambda (l), is the Greek letter often used to refer to an eigen-value in certain types of mathematical and statistical analyses.  The word eigen, like l , has several shades of meaning.  It usually means particular to, unique to, or  odd or strange in a particular, unique, and special way.  Since these descriptors apply to most data, all real systems, and yours truly, I  selected lambda as a symbol of my work (and life).
