	Conditional Reliability vs. Time and ~~Conditional Unreliability vs. Time shows the reliability or probability of failure over intervals of time. There are two options:~~

	* Vary Mission Time shows how the reliability or probability of failure would vary over different mission times if the system operated at a specific Start Time. The start time is an assumed value for the system age at the beginning of the mission. For example, a start time = 100 hours means that the origin of the plot corresponds to a system with a total age of 100 hours after a mission of 0 hours. Therefore, an x-axis value of 500 mission hours on that plot would correspond to a system with a total age of 600 hours after a mission of 500 hours.

	* Vary Start Time shows how the reliability or probability of failure would vary over different start times if the system operated within a specific Mission Time. The mission time is an assumed value for additional age a system will accumulate during the mission. For example, a mission time = 100 hours means that the origin of the plot corresponds to a system with a total age of 100 hours after a mission of 100 hours. Therefore, an x-axis value of 500 hours on that plot would correspond to a system with a total age of 600 hours after a mission of 100 hours.

==Parametric Recurrent Event Data Analysis Folios==
Weibull++ includes several plot types you can use to visualize the results of your parametric RDA analysis. You can create plots by choosing Recurrent Event Data > Analysis > Plots or by clicking the icon on the Main page of the control panel.

The features on the plot sheet are similar to the options available for all other Weibull++ plots. Features that are not applicable to parametric RDA analysis will be hidden or disabled. To learn how to customize a plot, see Plot Setup.

The following is a description of the plots types that can be created in a parametric RDA folio:
{{cumulative number of failures vs time}}

===Cumulative Failure Intensity vs. Time===
Cumulative Failure Intensity vs. Time plots the average rate of occurrence of failures over a period of time. The points represent the cumulative failure intensity calculated at each failure time in the data set and the line represents the cumulative failure intensity based on a simulation using the calculated model parameters. This shows how the rate of occurrence of failures increases, decreases or remains constant for that period of time.

===Instantaneous Failure Intensity vs. Time===
Instantaneous Failure Intensity vs. Time plots the rate of occurrence of failures over several instances of time. The line represents the instantaneous failure intensity based on a simulation using the calculated model parameters. This plot may be used to show how the rate of occurrence of failures has changed at a particular point in time.

===Conditional Reliability vs. Time===
Conditional Reliability vs. Time and Conditional Unreliability vs. Time shows the reliability or probability of failure over intervals of time. There are two options:

* Vary Mission Time shows how the reliability or probability of failure would vary over different mission times if the system operated at a specific Start Time. The start time is an assumed value for the system age at the beginning of the mission. For example, a start time = 100 hours means that the origin of the plot corresponds to a system with a total age of 100 hours after a mission of 0 hours. Therefore, an x-axis value of 500 mission hours on that plot would correspond to a system with a total age of 600 hours after a mission of 500 hours.

* Vary Start Time shows how the reliability or probability of failure would vary over different start times if the system operated within a specific Mission Time. The mission time is an assumed value for additional age a system will accumulate during the mission. For example, a mission time = 100 hours means that the origin of the plot corresponds to a system with a total age of 100 hours after a mission of 100 hours. Therefore, an x-axis value of 500 hours on that plot would correspond to a system with a total age of 600 hours after a mission of 100 hours.

===Conditional Unreliability vs. Time===
Conditional Reliability vs. Time and Conditional Unreliability vs. Time shows the reliability or probability of failure over intervals of time. There are two options:

* Vary Mission Time shows how the reliability or probability of failure would vary over different mission times if the system operated at a specific Start Time. The start time is an assumed value for the system age at the beginning of the mission. For example, a start time = 100 hours means that the origin of the plot corresponds to a system with a total age of 100 hours after a mission of 0 hours. Therefore, an x-axis value of 500 mission hours on that plot would correspond to a system with a total age of 600 hours after a mission of 500 hours.

* Vary Start Time shows how the reliability or probability of failure would vary over different start times if the system operated within a specific Mission Time. The mission time is an assumed value for additional age a system will accumulate during the mission. For example, a mission time = 100 hours means that the origin of the plot corresponds to a system with a total age of 100 hours after a mission of 100 hours. Therefore, an x-axis value of 500 hours on that plot would correspond to a system with a total age of 600 hours after a mission of 100 hours.
