Methods for Assessing Fish Populations

Fisheries managers are likely to assess fish populations at some point during the fisheries management process. Managers that follow the fisheries management process (see Chapter 5) might find their knowledge base insufficient during the steps of problem identification or management action and must assess a population before appropriate actions can be taken. Managers will implement some type of...

Statistical methods for assessing agreement

Survival methods: additional topics.

Survival analysis concerns outcome variables that are the times to the occurrence of events such as myocardial infarction, hospitalization for heart failure, or death. Rao and Schoenfeld1 give an excellent account of frequently used techniques in survival analysis, including Kaplan–Meier estimation of a single survival distribution, the log-rank test for comparing 2 survival distributions, and ...

assessing methods of normal heart sounds

listen to the heart sounds gives us valuable information about existence of disorder in heart rate and rhythm, ventricular fibrillation and movement of blood through valves. this required a lot of skills. so it is necessary to understand and apply these skills for nurses in cardiac and intensive care. abnormal sounds can be recognized by them. for facilitation this work, nurses should be have i...

Assessing Different Classification Methods for Virtual Screening

How well do different classification methods perform in selecting the ligands of a protein target out of large compound collections not used to train the model? Support vector machines, random forest, artificial neural networks, k-nearest-neighbor classification with genetic-algorithm-optimized feature selection, trend vectors, naïve Bayesian classification, and decision tree were used to divid...
