  2. Estimation (project management) - Wikipedia

    en.wikipedia.org/.../Estimation_(project_management)

    In project management (e.g., for engineering), accurate estimates are the basis of sound project planning. Many processes have been developed to aid engineers in making accurate estimates, such as Analogy based estimation; Compartmentalization (i.e., breakdown of tasks) Cost estimate; Delphi method; Documenting estimation results; Educated ...

  3. Spatial analysis - Wikipedia

    en.wikipedia.org/wiki/Spatial_analysis

    Spatial regression methods capture spatial dependency in regression analysis, avoiding statistical problems such as unstable parameters and unreliable significance tests, as well as providing information on spatial relationships among the variables involved. Depending on the specific technique, spatial dependency can enter the regression model ...

  4. Putnam model - Wikipedia

    en.wikipedia.org/wiki/Putnam_model

    B is a scaling factor and is a function of the project size. [3] Productivity is the Process Productivity, the ability of a particular software organization to produce software of a given size at a particular defect rate. Effort is the total effort applied to the project in person-years. Time is the total schedule of the project in years.

    en.wikipedia.org/wiki/Program_Evaluation_and...

    The program evaluation and review technique (PERT) is a statistical tool used in project management, which was designed to analyze and represent the tasks involved in completing a given project. PERT was originally developed by Charles E. Clark for the United States Navy in 1958; it is commonly used in conjunction with the Critical Path Method ...

  6. Uncertainty quantification - Wikipedia

    en.wikipedia.org/wiki/Uncertainty_quantification

    Simulation-based methods: Monte Carlo simulations, importance sampling, adaptive sampling, etc. General surrogate-based methods: In a non-instrusive approach, a surrogate model is learnt in order to replace the experiment or the simulation with a cheap and fast approximation. Surrogate-based methods can also be employed in a fully Bayesian fashion.

  7. Software development effort estimation - Wikipedia

    en.wikipedia.org/wiki/Software_development...

    Formal estimation model: The quantification step is based on mechanical processes, e.g., the use of a formula derived from historical data. Combination-based estimation: The quantification step is based on a judgmental and mechanical combination of estimates from different sources. Below are examples of estimation approaches within each category.

  8. Modifiable areal unit problem - Wikipedia

    en.wikipedia.org/wiki/Modifiable_areal_unit_problem

    Until a more analytical solution to MAUP is discovered, spatial sensitivity analysis using a variety of areal units is recommended as a methodology to estimate the uncertainty of correlation and regression coefficients due to ecological bias. An example of data simulation and re-aggregation using the ArcPy library is available. [13] [14]

  9. SEER-SEM - Wikipedia

    en.wikipedia.org/wiki/SEER-SEM

    D is staffing complexity - a rating of the project's inherent difficulty in terms of the rate at which staff are added to a project. E is the entropy - In days gone by entropy was fixed at 1.2. Next it evolved to 1.04 to 1.2 depending on project attributes with smaller IT oriented projects tending toward the lower.
