Experimental design testing multiple factors simultaneously in all combinations

The proportion of cells undergoing division within a population

A quantitative measure of uncertainty about an outcome of a draw from a probability distribution

Grouping of individuals based on body shape rather than species-level identification due to field identification constraints

Radar systems that transmit and receive both horizontal and vertical polarizations to characterize particle shape, orientation, and microphysical properties

Analysis of carbon and nitrogen isotope ratios to determine trophic position and dietary composition

Dating technique that determines cooling histories of rocks using temperature-sensitive radiometric systems

Experimental design where subjects choose between two alternative options to assess preferences

Method for quantifying the proportion of overall variance explained by different factors or pathways using R² calculations

Statistical approach using prior distributions and likelihood functions to make probabilistic inferences about model parameters

A method for calculating dominance based on an individual's relative number of wins or losses that is tolerant of missing pair-wise interactions and weights wins highly
