Imputation Approaches for Animal Movement Modeling
Henry R. Scharf, Mevin B. Hooten, Devin S. Johnson
The analysis of telemetry data is common in animal ecological studies. While the collection of telemetry data for individual animals has improved dramatically, the methods to prope…
Process convolution approaches for modeling interacting trajectories
Henry R. Scharf, Mevin B. Hooten, Devin S. Johnson +1
Gaussian processes are a fundamental statistical tool used in a wide range of applications. In the spatio-temporal setting, several families of covariance functions exist to accomm…
Basis Function Models for Animal Movement
Mevin B. Hooten, Devin S. Johnson
Advances in satellite-based data collection techniques have served as a catalyst for new statistical methodology to analyze these data. In wildlife ecological studies, satellite-ba…
Data Augmentation for Hierarchical Capture-recapture Models
J. Andrew Royle, Sarah J. Converse, William A. Link
Capture-recapture studies are widely used to obtain information about abundance (population size or density) of animal populations. A common design is that in which multiple distin…
Semiparametric Bivariate Zero-Inflated Poisson Models with Application to Studies of Abundance for Multiple Species
Ali Arab, Scott H. Holan, Christopher K. Wikle +1
Ecological studies involving counts of abundance, presence-absence or occupancy rates often produce data having a substantial proportion of zeros. Furthermore, these types of proce…
