Multilevel Modeling is a concise, practical guide to building models for multilevel and longitudinal data. Author Douglas A. Luke begins by providing a rationale for multilevel models; outlines the basic approach to estimating and evaluating a two-level model; discusses the major extensions to mixed-effects models; and provides advice for where to go for instruction in more advanced techniques. Rich with examples, the Second Edition expands coverage of longitudinal methods, diagnostic procedures, models of counts (Poisson), power analysis, cross-classified models, and adds a new section added on presenting modeling results. A website for the book includes the data and the statistical code (both R and Stata) used for all of the presented analyses.

The Trailways bus organization is one of the largest systems of independent motorcoach operators in the world.

Now through these historic photographs, bus and transportation enthusiasts can experience the enormous variety of bus makes and models used by the company, as well as many interesting and unusual designs.

Western Flyer Auto & Truck Body Works began producing buses in 1930 and through a number of name-changes continues today as New Flyer Industries. Because they served Canada and much of North America, the buses were built to stand up to the harsh winter climates they had to work in. This revered bus builder has become one of the dominant players in the transit bus manufacturing industry in North America, and a leader in hybrid bus manufacturing in the U.S. and Canada. New Flyer has been named as one of Canada’s most earth-friendly employers for 2008. From breaking new ground with low-floor buses to pioneering cleaner propulsion systems, innovation and excellence have taken New Flyer to the top of the industry. This book commemorates 80 years of these sturdy and attractive buses and trolley buses, and the companies that ran them, through vintage black and white photography along with a color section.
Hugo Young founded the Flxible Side Car Company in 1913 in Loudonville, Ohio. In the early 1920s, the mass production of automobiles lowered their cost to the point where sidecar-equipped motorcycles could no longer compete. The Flxible Company used this challenge as an opportunity to enter the bus-building business. The first Flxible bus was built in 1924, and was among only a few Flxibles built in the 1920s. The real boost in Flxible's bus production came in 1936 with the introduction of the Flxible Airway coach, mounted on a Chevrolet truck chassis. Read and see photos of the Flxible Airway coaches and other Flxible intercity buses like the Clipper, Visicoach, C-37, Starliner, Vistaliner, Hi-level models, Flxliner, and more.
