StatOracle–11 Analysis of Variance in R
Dispersion analysis — a powerful method (more precisely — an entire “bouquet” of methods) created by Ronald Fisher. This method is based on the possibility of decomposing the dispersion (English: variance) of a random variable into components caused by different …
StatOracle–12 Cluster Analysis in R
Cluster analysis — a method very frequently employed in zoological research. Unfortunately, in many instances its application is not the optimal choice, which is precisely why one must understand the distinctive characteristics of this method.
StatOracle–04 First Acquaintance with R
This chapter introduces the use of R and provides several simple examples of operations required for the analysis of biological data.
StatOracle–08 Descriptive Statistics and Distributions; Comparison of Distributions
Primary data base in R. What next? Before proceeding to analysis, it is often necessary to determine descriptive statistics and the distributions of the traits being studied.
Biology. Introduction to the specialty. Task III: Creating a table for collecting primary data
Canon of constructing a table for primary data collection: 1. Collection of primary data («answers of nature» to the researcher) — is a consequence of the necessity to obtain an answer to a certain question! 2. When constructing a table …
StatOracle–09 Comparing Samples in R
Comparing samples — one of the most common types of statistical analysis (currently under development)
StatOracle–05(S) Data Visualization in Statistica
The first (and sometimes — even the only one, since it provides answers to all questions) result of data analysis — is the construction of graphs, visualization of results. Here the data visualization in Statistica is explained using an example …
StatOracle–02 Foundation: canon of primary data collection and example PelophylaxExamples
How should a table for collecting primary data in biological research be organized? What programs can be used to analyze it?
StatOracle–01 Core Concepts of Biostatistics
The introductory chapter of a textbook devoted to statistical analysis of data in zoology and ecology. This textbook is intended for the corresponding section of a large practical course for fourth-year students of the Department of Zoology and Animal Ecology …

Ecology: biology of interaction. I-14. (supplement) Describing diversity of biosystems: classification, typology, ordination
Dynamic typology is based not only on analysis of an object’s observed state, but also on forecast (typically probabilistic) of its future dynamics. One path to its construction is analysis of phase space trajectories and stability basins.
