Estimator View

Model Parameter Estimation

The Estimator View allows a user to estimate parameter for a (new) model based on existing data.  Algorithms are now complete for parameter Estimation using SI, SIR, and SEIR models.

  1. Enter the Analysis Perspective
  2. Click on the Estimator Tab
  3. Click on the "Select" button to chose the directory that contains the data files you wish to analyze. These files should have the following  format.
  4. A dialog will launch allowing you to chose the folder. Select the folder by clicking "Select Scenario Folder" and then click "Next"

 

5. A second dialog will launch allowing you to chose from valid models appropriate to the data set you chose. If, for example, the data
contains columns for all S,E,I,R states, then any SEIR parameter estimator will appear on the list. Select and Estimator and click "Finish"

 

6. The Folder you chose will now show up on the "Scenario Folder" text field. Click "Estimate Parameters".

7. A bar chart graph will appear showing you estimates for the appropriate model parameters. In some case two bars will appear for each parameter as the estimator may
determine the best estimate fits within a range of values. For more information on the estimation algorithms please see the Eclipse STEM wiki.
