Quantitative Parasitology 3.0
This parasitology software provides statistically correct ways to analyse the highly aggregated (rightskewed) frequency distributions exhibited by parasites. QP3.0 is recommended to describe parasitic infections within a sample of hosts and to compare parasitic infections across different samples of hosts.
QP3.0 is free for distribution and use in education and science. When using it for academic purposes please cite:
"Reiczigel J, Rózsa L 2005. Quantitative Parasitology 3.0. Budapest. Distributed by the authors. "
Alternatively, you can consult and cite the paper that introduced this software:
Rózsa L, Reiczigel J, Majoros G 2000. Quantifying parasites in samples of hosts. Journal of Parasitology 86: 228232.
Note that a some of the methods incorporated in QP3.0 were either newly introduced or reconsidered in more recent articles listed below.
How to run
QP3.0 runs under Windows. After download, unzip the file and find a folder named 'QP30'. Do not remove the files from the folder. Within this folder, you just
• right click (i.e. use the right mouse button to click) the file named '_qp30.exe' • then select 'run as administrator'.
Why do we apply several different statistical tests in parallel with each other? How to choose the approprite statistical procedures for a particular study? Find a brief technical guide here.
Statistical tools available in QP3.0
1. To describe parasitic infection of a single sample of hosts:
2. To compare parasitic infections between two samples of hosts:
3. To compare parasitic infections among 3 or more samples of hosts:

Bug fixed There was a mistake slightly affecting the confidence intervals for mean intensity and mean abundance in a former version of Quantitative Parasitology. QP2.0 downloaded after 02. 04. 2003. and all copies of QP 3.0 are free of this error.
