CreoStat HB
is a company with the vision to make statistical programs easy to
use and available at reasonable prices. The intention is to encourage
and make it easier for small companies, students and researchers
to apply statistical thinking and methods. Much effort has been
made to create an intuitive interface demanding as few steps as
possible for an analysis. However, a basic understanding of statistical
concepts like hypothesis testing and confidence interval is necessary
to use the programs.

Due to a wide
range of statistical procedures, both statisticians by profession
and non-statisticians with knowledge of the most common statistical
methods, may find the software useful. As well as using it as a
stand-alone software it may be a good complement to the software
used for the statistical analyses.

The focus has
been on the planning of studies, surveys or other situations where
statistical analyses of the collected data will be performed.

Another focus
has been on calculating common tests and confidence intervals when
the complete dataset is not available. If summary statistics, e.g.
means, medians, standard deviations etc. are known, it will sometimes
be possible to calculate p-values and confidence intervals based
on these. This situation occurs frequently in publications of research
results where a particular p-value or a confidence interval may
be missing.

CreoStat HB
started in 1990 as a statistical consulting firm and with a development
of statistical software. Within the company there is a large experience of statistics in
pharmaceutical drug development and interactions with authorities.

Software by
CreoStat HB:

StudySize is a Windows application for calculating the sample size
needed in a study, survey, or experiment. It
can be used to study a range of scenarios when the plan is to test,
give an estimate, or calculate a confidence interval for the parameter
of interest. It comprises a wide range of procedures and give examples
how to perform the calculations for most of them in a separate document.
The results
are presented as tables or graphs and summarized in text to be copied
and pasted into slides or other documents.
