Thanks
for a great set of routines! It's impossible to imagine a life scientist who
wouldn't find something useful here! And the price is astonishing ... scarcely
more than the cost of production and shipping ...
Many of the routines will be useful to working biologists and statisticians and
a lot of them would be quite useful in upper-level biostatistics courses. The
most challenging exercise for me is trying to remember that Johnson has a
routine for or document on the problem you're facing! -- you suddenly need to
write a simulation involving bivariate normals ... now, can I just remember
that Johnson has a routine for that? Fortunately, however, Johnson supplies a
quick HTML overview that will lead you quickly to the document or routine of
interest.

I
appreciate the time and effort that you've put into developing an incredibly
useful set of programs---many of which aren't available anywhere else. The fact
that you're distributing them for essentially the cost of duplication and
mailing costs is even more amazing.
The
package and documentation are user-friendly, allowing investigators to begin
using the programs within minutes.
Paul Johnson's collection of statistical routines is a great partner to general statistical software. The timely production of the material in response to contemporary statistical literature is a very good service to the statistical community.
James Castle, Wildlife Biologist, BioResource Consultants, USA
This
software is excellent. I have used some of the programs and other I have
reviewed. I found them all to be easy to navigate and extremely useful. You
have my complete endorsement on both of these products.

Holt, Medical Statistician, National Health Service, United Kingdom
Generally, there are sufficient procedures that promise to have practical
utility as well as academic interest to attract my interest, as a recently
qualified (Advanced Masters) Medical Statistician. I look forward to exploring
them, and thank-you for making them available. I was also amazed, even the
second time, at how quickly they reached me!
Your
routines deal with problems epidemiologists and biostatisiticians face all the
time. As an epidemiologist I appreciate
having the routines at hand for the next time I need them. The sample size
routine for reliability studies alone was worth the cost. Thanks.

A nice collection of useful routines.

Many
thanks for the second CD. I'm stunned at how rapid the process is. I'm not a
statistician but an ecologist with some statistical background. While some
procedures are more advanced than what I need I look forward to exploring
others when I have time later on in the year. My initial impressions are that
the CD's are extraordinarily good value. The notes that accompany each
procedure are extremely helpful, especially the example data files and the
additional references.

Low price and high quality.
Dr. Paul Barrett, Chief Scientist, The
State Hospital, Carstairs, Scotland, United Kingdom
These are a very interesting collection of
literally hundreds of statistical and mathematical routines that will variously
be of use to those studying and working in general statistical, computational,
and biostatistical areas of investigation. The majority of routines have an
associated Acrobat pdf file, which describes the programmed feature, formulae,
computational steps, and invariably provides an example. What is impressive is
the number of key references littered throughout the texts - these alone are
worth their weight in gold. Navigating through the software and documents is
made extremely easy by a simple and clear web-interface. The software spans two
CDs - which can be purchased separately or jointly.
Sebastian E. Heath, VetMB, Ph.D. Washington DC, USA
Johnson delivers a concise compilation of many useful
statistical techniques. To familiarize the user with each procedure he provides
a description of the program, an example of an application and a sample data
base. Once familiar with the statistical application the user can then simply
plug in his/her data and perform an analysis. This easy-to-use compilation
should be useful to students, teachers and researchers who want to focus on
analyzing data and interpreting results than spending hours of valuable time
searching for syntax errors in programs they had to write themselves.
Paul Jurena, Ph.D. Post Doc, Dept. of Rangeland Ecology and Management,
Texas A&M University, USA
I'm very impressed with the documentation and instructions. Thanks for your software.
Daryl Nydam, DVM, Ph.D. Dept. of Population Medicine and Diagnostic
Sciences, Cornell University, USA
A large and useful suite of biostatistical routines priced such that you can
hardly afford not to purchase them.
Dr. Dario Gregori, Department of Economics and
Statistics, University of Trieste, Italy
What I found to be very exciting about this collection is the impressive coverage of the most advanced techniques currently used in medical research, with a very detailed and well-organized description of their usage, both from a technical and a statistical point of view.
