(4.0a version, 2003)
contains information on f o r m
u l a e and p r o c

Former:
Chief of Animal Health Service, Food
and Agriculture Organization
of the United Nations (FAO),
EPIZOO is applicable on any
animal species, any disease at any time and in any place.
The methods have been tested and used in
practice for animal population health and disease analyses and control
programmes at local, national and international levels. The software is
applicable to any species of animal kingdom, i.e. including Homo sapiens. EPIZOO software is available free of charge
in internet - www.cbox.cz/vaclavkouba/software/software.zip.
I N F O R M A T I O N
AND I N S T R U C T I O N S:
a) EPIZMETH
describes methods - formulae, their components and calculation procedures of indicators as well as results
construction used in EPIZOO software
package for animal population health analysis and programming.
b) In selected
generally known basic statistical methods are mentioned the references to bibliographical sources
only.
c) EPIZMETH
explanatory structure and menu are compatible with EPIZOO.
d) Formulae
symbols: capital letter = numeric variable; letter(s) following by '$' = variable in a form of text (string);
variable following by '(I)' = loop component of a set of variables (sequence of
instruction 'again and again') usually
introduced by 'FOR I=1 TO N'.
e) Arithmetic
operators: + addition; - subtraction; * multiplication; / division; ^ exponentiation; SQR =
square-root function.
f) Abbreviation
'epi.' = epizootiological or epidemiological.
g) For printing under
MS DOS using PRINT SCREEN key or under WINDOWS a word processing software *) to be used.
h) More
information on EPIZOO see in www.cbox.cz/vaclavkouba
and in author's articles published in:
- Rev.sci.tech. Office International des
Epizooties, 1994, 13 (3), 637-650

1995, 73 (1), 77-83
- Rev.sci.tech. Office International des
Epizooties, 1997, 16 (3), 793-799.
j) EPIZOO can be
started by going out from EPIZMETH and keying 'epizoo'.
k) The software
may be freely copied.
-----------------------------------
*) Notes: Open a
new file in WORD where the copied parts to
be pasted; place cursor on the upper bar
of EPIZOO ( EPIZMETH) window and press right mouse button; select EDIT - MARK;
place cursor in the EPIZOO (or EPIZMETH) window left upper corner and pressing left mouse button highlight the contents
to be printed; place cursor on the upper EPIZOO (EPIZMETH) window bar and press right mouse button; select EDIT
- COPY to Enter; open the WORD file; locate cursor where the window contents to be printed; select EDIT - PASTE; select FILE
- PRINT.
EPIZOO and EPIZMETH under MSDOS have been
using full screen. Under WINDOWS they start using smaller part of the screen;
for EPIZOO (EPIZMETH) window expanding into full screen following procedure to
be used: place cursor on the upper EPIZOO (EPIZMETH) window bar and press right
mouse button; select: PROPERTIES – DISPLAY OPTION – FULL SCREEN – OK – APPLY
PROPERTIES – SAVE PROPERTIES for future
windows with the same title – OK.

8-SELECTED SAMPLING METHODS FOR POPULATION HEALTH INVESTIGATIONS
1-Random numbers for selection of
representative animals/herds
2-Sample size for detecting presence of
a disease in a population
3-Sample size for estimating prevalence
in large population
4-Sample size for estimating prevalence
using confidence interval
5-Sample size for estimating prevalence using
absolute difference
6-Sample size for estimating prevalence
in finite population
7-Sample size for detecting difference
between two prevalences
8-Sample size for estimating mean of
population health phenomena - I.
9-Sample size for estimating mean of
population health phenomena - II.
10-Sample size for detecting difference
between two means
11-Stratified sampling for population
health investigations
12-Estimating prevalence from simple and
cluster random samples
13-Probability of failure to detect
diseased animals
Note: These sampling methods do not consider the sensitivity of the
tests. Its
value lower than 1 requires higher number of at random selected sampling
units.
