MODELTEST: testing the model of DNA substitution

open access: yesBioinform., 1998
SUMMARY The program MODELTEST uses log likelihood scores to establish the model of DNA evolution that best fits the data. AVAILABILITY The MODELTEST package, including the source code and some documentation is available at http://bioag.byu. edu/zoology/

Response-surface-model-based system sizing for nearly/net zero energy buildings under uncertainty [PDF]

open access: yes, 2018
Properly treating uncertainty is critical for robust system sizing of nearly/net zero energy buildings (ZEBs). To treat uncertainty, the conventional method conducts Monte Carlo simulations for thousands of possible design options, which inevitably leads

MODELING MODELING [PDF]

open access: yesJournal of the Experimental Analysis of Behavior, 1999
Models are tools; they need to fit both the hand and the task. Presence or absence of a feature such as a pacemaker or a cascade is not in itself good. Or bad. Criteria for model evaluation involve benefit‐cost ratios, with the numerator a function of the range of phenomena explained, goodness of fit, consistency with other nearby models, and ...

Identification and validation of stable reference genes for quantitative real time PCR in different minipig tissues at developmental stages

open access: yesBMC Genomics, 2022
Background Quantitative real time PCR (qPCR) is a powerful tool to evaluate mRNA expression level. However, reliable qPCR results require normalization with validated reference gene(s).

A Theoretical Extension of the Technology Acceptance Model: Four Longitudinal Field Studies

open access: yesManagement Sciences, 2000
The present research develops and tests a theoretical extension of the Technology Acceptance Model (TAM) that explains perceived usefulness and usage intentions in terms of social influence and cognitive instrumental processes.

A new look at the statistical model identification

open access: yes, 1974
The history of the development of statistical hypothesis testing in time series analysis is reviewed briefly and it is pointed out that the hypothesis testing procedure is not adequately defined as the procedure for statistical model identification.

Multiyear analysis uncovers coordinated seasonality in stocks and composition of the planktonic food web in the Baltic Sea proper

open access: yesScientific Reports, 2023
The planktonic realm from bacteria to zooplankton provides the baseline for pelagic aquatic food webs. However, multiple trophic levels are seldomly included in time series studies, hampering a holistic understanding of the influence of seasonal dynamics

PER1 Phosphorylation Specifies Feeding Rhythm in Mice

open access: yesCell Reports, 2014
Organization of circadian behavior, physiology, and metabolism is important for human health. An S662G mutation in hPER2 has been linked to familial advanced sleep-phase syndrome (FASPS).

Model selection and multimodel inference : a practical information-theoretic approach

open access: yes, 2003
The second edition of this book is unique in that it focuses on methods for making formal statistical inference from all the models in an a priori set (Multi-Model Inference). A philosophy is presented for model-based data analysis and a general strategy
