Development of a Car -Following Model to Simulate Driver and Autonomous Intelligent Cruise Controlled Vehicular Traffic Flow
… of a mix of driver controlled (DC) and AICC vehicles as well as all AICC vehicles. INTELSIM algorithm provided stability in AICC platoons and performed well in a variety of traffic situations including stop-and-go conditions. AICC vehicles can provide volumes of up to 7400, 5200 and 3100 …

Criteria for evaluating model deficiency for groundwater models and the effects of eliminating deficient models on multi-model analysis using AICC, KIC, AIC, and BIC
… are designed to evaluate how components of AIC, AICc, BIC, and KIC rank models and assign model probabilities, and to demonstrate how removing deficient models improves MMA results. Synthetic models are used to represent true but unknown systems in contrast to experimental models that are created …

Relative importance of Conservation Reserve Programs to mayfly, stonefly, and caddisfly species richness in the Kaskaskia River basin of Illinois
… in an Akaike information criterion analysis (AICc) to construct a set of 13 best regression models accounting for variance in EPT basin richness. AICc importance values and hierarchical partitioning revealed five important variables associated with EPT richness: Link (number of first order …

Revised distributional estimates for the recently discovered olinguito (Bassaricyon neblina), using museum and science records
… were selected via two different approaches, AICc and performance on withheld data. The occurrence data used here show climatic signals different from those for data used in the original description of the species. The AICc-optimal model aligned more closely with current knowledge of the …

The distribution and diversity of an entire assemblage of Plecoptera (stoneflies) inhabiting Indiana, USA
… variables, reduced from 116 and subjected to AICc Importance and Hierarchical Partitioning. AICc Importance revealed four variables associated with Plecoptera species richness, topographic wetness index, HUC8 area, percent soil hydrologic group C/D, and percent historic wetland ecosystem. …

The Ecological Effects of Cattle Grazing on Reptiles and Small Mammals in a San Joaquin Valley Grassland
… models included: 1) <em>Bare soil cover </em>(AICc = 28.12), 2) <em>Holes </em>(AICc = 29.76), and 3) <em>Bare soil cover</em> + <em>Holes </em>(AICc = 29.90). Shrubs, bare soil cover and small mammal burrow density were all positively associated with <em>U. stansburiana</em> presence at array …

The Effect of Landscape Variables on Adult Mosquito (Diptera:Culicidae)Diversity and Behavior
… a higher disease risk using information theory (AICc). The plains and coastal regions as well as the developed areas have a relatively higher risk of disease. Florida is a fire maintained habitat, but has been fire suppressed for the last century. Archbold Biological Station (ABS) has used …

Comparison of parametric models using right censored data for breast cancer patients
… from corrected Akaike Information Criterion (AICc), Bayesian Information Criterion (BIC) and mean square error (MSE). Based on the model selections, the log-logistic model found to be the best model with smallest value in AICc, BIC, and MSE. Besides that, a simulation study was also carried …

"MODEL COMPLEXITY AND VARIABLE SELECTION IN MAXENT NICHE MODELS: ANALYSES FOR RODENTS IN MADAGASCAR"
… ENMs: an information-criterion approach (AICc) and a sequential approach that assesses model performance on withheld data. I do so for a single species using two datasets, one with all available occurrence records, and the other with spatially filtered occurrence records (expected to …

Habitat Resource Selection By Greater Sage Grouse Within Oil and Gas Development Areas in North Dakota and Montana
… 0-m VOR, 1-m VOR grass height, and year affect (AICc weight = 0.54). When I compared the area of intense use to areas of relative non-use, I found that there were four competing models; the top model included total percent vegetation cover and grass height (AICc weight = 0.25). When I compared …

Within-fire patchiness associated with prescribed burning in the northern Jarrah forests of Western Australia
… to produce a list of candidate models. The AICc indicated which models were the most parsimonious or plausible candidate models (AICc < 2). Structured Equation Modelling (SEM) was completed to determine which variables in the ‘most parsimonious’ model were the greatest contributors to the …

EFFECTS OF SCALE AND HABITAT MANAGEMENT ON GRASSLAND BIRD RESPONSE IN CONSERVATION RESERVE PROGRAM FIELDS IN NORTHWEST ILLINOIS
… of nest survival for red-wings (50.58 ∆AICc = best temporal model) and dickcissels (2.28 ∆AICc = best temporal model) in addition to habitat covariates. In 3 of 4 analyses ≥2 habitat scales were better predictors of nest survival over one scale. For ground nesters the patch scale was be …

A modified approach for obtaining sieve bootstrap prediction intervals for time series
… estimated by using a model procedure such as the AICC. Existing sieve bootstrap methods in general, however, produces liberal prediction intervals due to several factors, including the use of residuals that underestimate the actual variance of the innovations and the failure of the methods to …

Experimental Evaluation of Three Backward Transit Time Distributions (bTTD) for Solute Storage and Release During Hyporheic Exchange
… Based on measures of model fit and parsimony (AICc), in all 47 experiments hyporheic exchange was best represented by either the Gamma or exponential distributions. Further, values for key process variables, including hyporheic exchange flux and the Gamma distribution's shape parameter are …
