Quantitative Parasitology 2.0


This parasitology software provides statistically correct ways

to describe parasitic infection of a sample of hosts, and
to compare parasitic infections between (among) different samples of hosts.


free download for Windows (Win 98 and above) 


free download for Mac (OS X or above) 


QP 2.0 is free for distribution and use in education and science. However, when using it for academic purposes please cite: Reiczigel, J. & Rózsa, L. 2001: Quantitative Parasitology 2.0. Budapest. Distributed by the authors.

As a theoretical background, you can consult and cite:
Rózsa, L., Reiczigel, J. & Majoros, G. 2000: Quantifying parasites in samples of hosts. Journal of Parasitology, 86, 228-232.

Statistical tools available in QP 2.0

to describe parasitic infection of a single sample of hosts:

Descriptive statistics (No. of hosts, prevalence, mean & median intensity, variance/mean)
Exact confidence interval for the prevalence (Clopper - Pearson),
Bootstrap (BCa) confidence interval for the mean intensity (Appendix I),
Exact confidence interval for the median intensity (Appendix II),
Aggregation indices (variance/mean, index of disrepancy, and k of the negative binomial),
Bootstrap (BCa) confidence interval for the mean abundance,

to compare parasitic infections between (or among) two (or more) samples of hosts

Fisher's Exact Test to compare Prevalences,
Chi-square Test to compare Prevalences,
Bootstrap t-Test to compare Mean Intensities (for 2 samples only, Appendix III),
s Median Test to compare Median Intensities (Appendix IV),
Bootstrap t-Test to compare Mean Abundances (for 2 samples only).

(Appendices are those of the paper cited above.)

Why do we need to use several tests paralelly? Click here to see a Brief Guide


All but one statistical modules were designed by J. Reiczigel.
Module "Aggregation indices" was designed by L. Rózsa.

Are you going to develop a new procedure? Please consider sharing it with others.
Send it by an e-mail and we'll publish it for you at this web-site.

BUGS fixed:

There was a mistake slightly affecting results of confidence interval for mean intensity and confidence interval for mean abundance. Unfortunately, due to lack of a minus sign in an "error correction", we doubled the error instead of removing it. Sorry. QP 2.0 downloaded after 02. 04. 2003. is free from this problem.
