An analytical process by which the results and conclusions of an economic analysis are assessed for robustness
systematic procedure for estimating the effects on the outcome of a study of the chosen methods and data
The concern with how the solution changes if some changes are made in either the data or in some of the solution values (by fixing their value) Marginal analysis is concerned with the effects of small perturbations, maybe measurable by derivatives Parametric analysis is concerned with larger changes in parameter values that affect the data in the mathematical program, such as a cost coefficient or resource limit
An analytical procedure to determine how the results of a study would change if the facts were different or different studies included This is chiefly important in meta-analysis or complex techniques such as decision analysis and cost-effectiveness analysis
Determination of the extent to which model behavior (output) varies as model parameters are varied
In its narrow sense, computing or approximating the jacobian of the simulator at the `best' input However, in use this term seems to be muscling in on the territory of Uncertainty analysis [JCR, 17 04 00]
used to recognize the effects of a user-defined design variable on the analysis results
a systematic and comprehensive test to evaluate how changes in the parameters of a model affect the model's output Often used to identify influential parameters
A risk analysis technique in which key variables are changed one at a time and the resulting changes in the NPV and IRR are observed
presentation of possible results and ways to create the result in a process which involves uncertain factors by assigning different values for these factors
Used in life cycle cost (LCC) analyses to determine how robust a particular alternative is, and how sensitive the overall cost is to certain variables
Technique used to determine the effects on net income or cash flow due to changes in assumptions, i e , "what-if" analysis
A process of examining specific tradeoffs that would result from making changes in single elements of a plan alternative
A method used by economists (and others) to test whether variations in assumptions affect the conclusions of a cost-benefit or similar study {2} Use your browser's "BACK" button to return to the page you were viewing previously
A method of analyzing the results of a sensitivity test Because a sensitivity test does not provide individual measures of the critical stress levels of members of the sample, it is not possible to compute an estimate of the mean in the normal manner of adding up the values and dividing by the sample size It is similarly difficult to calculate the estimate of the standard deviation
Varying the value of a parameter to find the extent to which the change affect the results of the analysis If a small change in an assumption results in a proportionately greater change in the results, then the results are said to be "sensitive" to that assumption or parameter
