Introduction[ edit ] The scientific observation cycle. In its most basic forms, model selection is one of the fundamental tasks of scientific inquiry.
Determining the principle that explains a series of observations is often linked directly to a mathematical model predicting those observations. For example, when Galileo performed his inclined plane experiments, he demonstrated that the motion of the balls fitted the parabola predicted by his model[ citation needed ].
Of the countless number of possible mechanisms and processes that could have produced the data, how can one even begin to choose the best model?
The mathematical approach commonly taken decides among a set of candidate models; this set must be chosen by the researcher.
Often simple models such as polynomials are used, at least initially[ citation needed ]. Once the set of candidate models has been chosen, the statistical analysis allows us to select the best of these models.
What is meant by best is controversial. A good model selection technique will balance goodness of fit with simplicity[ citation needed ]. More complex models will be better able to adapt their shape to fit the data for example, a fifth-order polynomial can exactly fit six pointsbut the additional parameters may not represent anything useful.
Perhaps those six points are really just randomly distributed about a straight line.
Goodness of fit is generally determined using a likelihood ratio approach, or an approximation of this, leading to a chi-squared test. The complexity is generally measured by counting the number of parameters in the model.
Model selection techniques can be considered as estimators of some physical quantity, such as the probability of the model producing the given data.
The bias and variance are both important measures of the quality of this estimator; efficiency is also often considered. A standard example of model selection is that of curve fittingwhere, given a set of points and other background knowledge e.

Inclusion and Exclusion Criteria Inclusion criteria = attributes of subjects that are essential for their selection to participate.
Inclusion criteria function remove the influence of specific confounding variables. eg., fitness, menstrual cycle phase, use of oral contraceptives.
Project Risk: Project risk must be assessed and evaluated as part of the project selection criteria which establishes the balance of risks vs. rewards in the business case. Often the use of a project risk rating comes in the form of a weighting factor rather than a direct project ranking criteria to .
So as a Project Manager, what should you consider when you are doing project selection? Which are the most common project selection methods? In this article we are going to overview the different project selection methods and when is the best occasion for using each project selection method.
