Research studies in veterinary epidemiology typically are directed toward an evaluation of the relationship between an outcome or response variable and one or more risk factors. Frequently, the relationship of interest is adjusted for other known risk factors or other nuisance information such as age,...
Sensitivity analysis of different methods of coding taxonomic polymorphism: an example from higher-level bat phylogeny. Cladistics 18:571-584.Simmons, N. B. and J. H. Geisler. 2002 . Sensitivity analysis of different methods of coding taxonomic polymorphism: An example from higher-level bat ...
We then present an example of how to model CAC using this framework. We demonstrate that utilizing this type of modeling strategy can result in traditional predictors of CAC (e.g. age, gender, and high-density lipoprotein cholesterol), exerting a different impact on the two different, yet ...
Excel Solver[1]is an optimization tool that can be used to determine how the desired outcome can be achieved by changing the assumptions in a model. It is a type ofwhat-if analysisand is particularly useful when trying to determine the “best” outcome, given a set of more than two assu...
This example is not meant to be an ideal analysis of the Fisher iris data. In fact, using the petal measurements instead of, or in addition to, the sepal measurements may lead to better classification. Also, this example is not meant to compare the strengths and weaknesses of different cla...
In statistics and probability theory, the Bayes’ theorem (also known as the Bayes’ rule) is a mathematical formula used to determine the conditional probability of events. Essentially, the Bayes’ theorem describes theprobabilityof an event based on prior knowledge of the conditions that might be...
Answer to: Explain what a "level" is in relation to an independent variable. Give an example of an independent variable and its levels. By signing...
Under this change of variable, the given indefinite integral becomes ∫(u2−3) u2 du = ∫u4 du−3∫u2 du =u5/5−u3 =(x2+3)5/2/5−(x2+3)3/2 because u=x2+3−−−−−−√. Of course, there are settings in which the addition of an arbitrary constant...
Key Elements of Project Estimation Three key elements must be considered in any project estimate. These are sometimes called the “project management triangle” or the “3 pillars” of an estimation. These three elements are important for providing realistic expectations and ensuring a project’s ove...
A random variable is a number whose value is unknown and can be changed to evaluate an outcome, such as the future price of a stock. What Is a Random Variable? A random variable is one whose value is unknown or a function that assigns values to each of an experiment’s outcomes. Rando...
