| </b></p> |
| <p>The <em>Estimator View</em> 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. </span> |
| <ol> |
| <li>Enter the <a href="../perspectives/analysis.html">Analysis Perspective</a></li> |
| <li>Click on the Estimator Tab</li> |
| <li>Click on the "Select" button to chose the directory that contains the |
| data files you wish to analyze. These files should have the following |
| <a href="csvloggerview.html"> format.</a></li> |
| <li>A dialog will launch allowing you to chose the folder. Select the folder |
| by clicking "Select Scenario Folder" and then click "Next"</li> |
| </ol> |
| </p> |
| <p><img border="0" src="img/Estimator1a.jpg" width="1000" height="800"></p> |
| <p>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<br> |
| 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"</p> |
| <p> </p> |
| <p><img border="0" src="img/Estimator1b.jpg" width="1000" height="800"></p> |
| <p>6. The Folder you chose will now show up on the "Scenario Folder" text field. |
| Click "Estimate Parameters".</p> |
| <p><img border="0" src="img/Estimator2.jpg" width="1000" height="800"></p> |
| <p>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<br> |
| determine the best estimate fits within a range of values. For more information |
| on the estimation algorithms please see the |
