analysis of data in Natural Sciences
Usually I collaborate performing the statistical analysis of data in research projects in biology. Almost all the problems that I have worked I used a mixture of methods of statistical inference, multivariate analysis, and methods of descriptive statistics.
that I have worked with have been very different nature: physiology of fungi [1c,
plant virology [4c], ecology of spiders
populations of cells [6c], geology [7c], botany [8c, 9c], vascular system in mammals [10c], diagnosis of depression through the multivariate

issue is the analysis of data from computer simulation experiments in
artificial life and artificial intelligence. Obviously these data
differ from those obtained in experiments performed in nature or in the
laboratory. Statistical analysis of data
from simulation experiments requires some care: in  we reviewed some general protocols applied to evolutionary
A book about
statistical methods in behavioral biology
In 1995 I wrote
in collaboration with specialists in animal behavior the book entitled Statistical Methods in Behavioral
Biology (Transl:. In spanish, Métodos
Estadísticos en Biología del Comportamiento).
The book, eminently practical, deals with a simple and direct language, the theoretical foundation and application of statistical techniques in the field of Behavioral Biology, whether animal or human. The book is primarily aimed at students from Psychology, Biology, Medicine and, in general, all those who are interested in the statistical analysis. The book contains many examples that have been taken from these disciplines, to show the use of statistical methods. As innovation is noteworthy that is the first book in spanish incorporating a 'floppy disk' with the programs for the statistical tests described therein, and is the first to describe circular statistics techniques, useful in the study of animal orientation and biological rhythms.
The book is accompanied by 'PhiStat 1.0' program: a collection of programs in Turbo Pascal (MS-
analysis of laughter and diagnosis of depression
There are no
studies in psychiatry attempting the use of laughter as a diagnostic
tool. In the present study [11c, 12c] we extracted nine temporal and acoustic variables from
laughter episodes, looking for establishing better pattern-
