Advanced Statistics for Health Research provides a rigorous geometric understanding of models used in the analysis of health data, including linear and non-linear regression models, and supervised machine learning models. Models drawn from the health literature include: ordinary least squares, two-stage least squares, probits, logits, Cox regressions, duration modeling, quantile regression and random forest regression. Causal inference techniques from the health literature are presented including randomization, matching and propensity score matching, differences-in-differences, instrumental variables, regression discontinuity, and fixed effects analysis. Codes for the respective statistical techniques presented are given for STATA, SAS and R.

Field Guide to the Sedges of the Pacific Northwest is an illustrated guide to all 169 species, subspecies, and varieties in the genus Carex that grow in the wild in Oregon and Washington. Most of these species are found throughout the Pacific Northwest and California. This updated second edition includes eight additional species documented in the region since the guide was first published, along with an improved identification key, updated nomenclature and taxonomy, revised range maps, and improved illustrations.
Sedges can be difficult to identify, with differences between species based on small, technical characters. This comprehensive guide contains identification keys, descriptions, more than 650 color photographs, and distribution maps for each species, providing users with helpful tools and tips for identifying the plants in this challenging group. Information about sedge ecology, habitat, management and restoration, ethnobotanical uses, and propagation enhances the guide's utility.
Field Guide to the Sedges of the Pacific Northwest provides an invaluable resource for botanists, land managers, restoration ecologists, and plant enthusiasts. And, as the genus Carex becomes increasingly important amongst landscapers, nurseries, and gardeners, the guide will serve as a handy tool for choosing Northwest natives for the garden.
