Overview
Dynamic Sensitivity analysis for Likelihood is used to dynamically change the likelihoods of the threats to determine how these changes affect the likelihoods of the events.
In Riskion, we refer to threats, causes, hazards, and sources interchangeably. While they may have slightly different nuances depending on the context in which they are used, they serve the same purpose -- they are all threats/sources of risk (for Risk Events) or sources of opportunity (for Opportunity Events).
In our sample model, we are using the terminology "Source(s)".
The bars at the left represent the likelihood of the sources, while the bars at the right are the likelihood of the events.
Dynamic Analysis for the Overall Events Likelihoods
By dragging the source's likelihoods back and forth in the left column, the likelihoods of the events will change in the right column.
The black 
markers on the source and event bars indicate the original sources' and events' likelihoods.
After temporarily changing the likelihoods of one or more of the sources, you can press the 
reset icon.
By selecting an element in the hierarchy other than the top node, you can see the results due to this element rather than the overall results due to the "Sources" node.
Dynamic Analysis for the Events Likelihoods due to Human Factor
You can hide the Sources Hierarchy at the left using

Select Participants and Groups
You can select to display results for one participant or group using 
Clicking the 
button will open a window where you can select a participant or a group.
You can use the prev
and the next 
buttons to cycle through each participant or group.
Filter Events
By default, all events are displayed.
You can select to display the top or bottom 5, 10, or 25 events based on the "All Participants" group likelihoods.
The Advanced filter, allows you to select a specific number for the top N, and base it on another group or participant.
The select /deselection option, allows you to check/uncheck the events.
The filter by events attributes, filter the events base on the attributes specified on the Events page.
The show risks only / Show opportunities only are applicable for the Mixed model where events can be Risk or Opportunity.
Events Components
Checking the
displays the breakdown of each of the source's contributions or share to the likelihoods of each of the events
The breakdown colors of the event bars at the right corresponds to each of the sources at the left.
Active Sorting (Keep Sorting)
Active Sorting is only enabled when Events are Sorted by Likelihoods.
Checking the Active Sorting checkbox actively re-sorts the events as the source likelihoods are being adjusted.
When the Active Sorting is OFF, the initial sorting of the events will be remembered.
Change Events Color
Clicking on the event bar will open a color picker where you can select and change the color assignment.
You can also change colors from the Events and Threats/Sources Grid.

Advanced Mode Options
When the Advanced mode is ON, you will see the advanced options of the page you are currently working on.
1. Combined Input Option (CIS)
If the Combined Input Option (CIS) is ON then results for individuals are computed by combining the likelihoods (or impacts) derived from judgments/ratings for which they had roles, with the combined results for any parts of the model where they did not have a role.
2. Apply User Priorities
If priorities (weights) have been specified for participants, you can use the "User Priorities" check box which enables you to apply or ignore these priorities in calculating the results.
3. Synthesize Events WRT top-node
This option is available on all the Sensitivity screens and can only be enabled when a non-covering node other than the top node is selected on the hierarchy tree.
Enabling this option allows to temporarily change the likelihood (or impacts) of the children of the selected node and see how these changes will affect the overall likelihood (or impacts, or risks) of the events. If this is OFF, we can then see the change of the likelihood (or impacts, or risks) of the events WRT the selected node.
4. Show Markers
Checking the 
checkbox displays red and blue markers on the events bars indicating the likelihood when the selected source is dragged to the maximum (100% ) or minimum (0% ) respectively.
The selected source in the example above is the "Human Factor" as indicated by its light gray background. When the "Human Factor" bar is dragged to the maximum (100%), the events' bars at the right will be filled up to where the red marker is. When it is dragged to the minimum (0%), the events bars at the right will be filled up to where the blue marker is.
Depending on the event, red might be on the right and blue on the left, or vice-versa.
