This is a tool that is located on the Sample Adequacy section of the Sample Adequacy tab.
Function
The Sample Risk Analysis interface () is used to review Functional System, Urban Code, and Volume Group stratums to locate samples that are near the upper or lower ranges of a volume group.
Section
The Sample Risk Analysis interface is divided into 4 sections: Data Table Information, Risk Analysis Parameters, Sample Risk Stratum Table, and Sample Risk Detail Table.
(1) Data Table Information
The Data Table Information section contains general information about the currently selected HPMS Data Table. This section hosts the Data Table and Year dropdown controls.
(2) Risk Analysis Parameters
The Risk Analysis Parameters section provides the user with three search options, or controls:
| Control | Used To... |
| At Risk Samples have AADT within % of Volume Group Upper/Lower Bounds | Identify AADT values within a range of the limits of a volume group that are at risk of moving to a different volume group; required. |
| Show Stratums with At Risk Samples comprising % of the Number of Required Samples | Filter stratums that do not have a certain percentage of at-risk samples; select a symbol from the picklist, then specify a percentage in the textbox. |
| Show Stratums with At Risk Samples | Filter stratums that do not have a certain number of at-risk samples; select a symbol from the picklist, then specify an amount in the textbox. |
| Perform Analysis Button | Instigate the HPMS data analysis; the Sample Risk Stratum Table will be populated with information based on the parameters specified. |
(3) Sample Risk Stratum Table
The Sample Risk Stratum Table displays the number of required samples, provided samples, at-risk samples, and the percentage of at-risk samples to provided samples for each stratum based on the parameters set in the Risk Analysis Parameters. There are some important elements in this section:
| Element | Used To... |
| Export to Excel Link | Display the information as a report. |
| Rows Returned Count | Display the number of rows in the table. |
By clicking on a row in the Sample Risk Stratum Table, the row will highlight, and the Sample Risk Detail Table section will be populated with data.
(4) Sample Risk Detail Table
The Sample Risk Detail Table will remain blank until one of the rows in the Sample Risk Stratum Table is selected. When a row is selected, the Sample Risk Detail heading will change to reflect that selection, and the Sample Risk Detail Table will be populated with samples that can be found in the selected HPMS Data Table. Users can also opt to select the "Only Show At Risk Samples" checkbox which will exclude samples that are not at risk.
Workflow
There is a Workflow equivalent of this article in the Help Guide. In that article, the information on Sample Risk Analysis is focused more on steps rather than sections of the interface. Click here to view that article.
