Represents a model resource.

Constructors

Name Description
cModel Creates an instance of the cModel class.
cModel() A parameterized constructor for the cModel class. (.NET only)


Methods

Name Description
Bounds_FailureRate Calculates the bounds on the failure rate at a specified time for an associated cModel object. Returns a BoundsValues object that represents the confidence bounds.
Bounds_MeanTime Calculates the bounds on the mean time to failure for an associated cModel object. Returns a BoundsValues object that represents the confidence bounds.
Bounds_Parameters Calculates the confidence bounds on the parameter estimates of an associated cModel object. Returns a ParamBoundsValues object that represents the confidence bounds on the parameter estimates.
Bounds_Reliability Calculates the bounds on the reliability at the specified time for an associated cModel object. Returns a BoundsValues object that represents the confidence bounds.
Bounds_Time Calculates the bounds on the time at which a specified reliability will be achieved for an associated cModel object. Returns a BoundsValues object that represents the confidence bounds.
Bounds_Unreliability Calculates the bounds on the probability of failure at a specified time for an associated cModel object. Returns a BoundsValues object that represents the confidence bounds.
FailureRate Returns the failure rate at the specified time. Double
MeanTime Returns the mean time to failure. Double
Parameters Returns an array of ParamValues objects that represent the parameter name and value pairs of an associated cModel object.
Pdf Returns the y-value of the pdf at the specified x-value (time). Double
Reliability Returns the reliability at the specified time. Double
SetConfidenceLevel Sets the confidence level to use in confidence bounds calculations for published models. Returns a Boolean value; when true, indicates that a confidence level has been set.
ScaleParameter_A For ALTA models, returns the scale parameter at the use stress level. Double. Returns 0 if the model is not an ALTA model.
SetModel Sets the model type, category, name and parameters of an associated cModel object.
SetUseStress For ALTA models only. Specifies the use stress level(s) to use for calculations.
Time Returns the time at which a specified reliability will be achieved. Double
Unreliability Returns the probability of failure at the specified time. Double
