Data set name
|
The unique name to assign to the data set. By default, the name is New Data Set. If a data set with this name already exists, the name assigned is New Data Set (X), where (X) is the next available numeric value. You can specify any unique name that you want to use.
|
Data type
|
The type of data in the data set. The choices are Exact Times and Interval. The default is Exact Times.
|
Suspensions
|
Indicates whether the data to import contains only failures or both failures and suspensions. When this checkbox is cleared (default), only failures are present. When this checkbox is selected, both failures and suspensions are present.
|
Grouped
|
Indicates whether the data to imported is grouped. When this checkbox is cleared (default), the data is not grouped. When this checkbox is selected, the data is grouped.
|
Stress type
|
Indicates the type of stress applied to accelerate component aging. Choices are Constant and Time Varying (CEM). The default is Constant. When stresses vary over time, you use stress profiles. For more information, see Stress Profiles.
|
Stress model
|
The model to use to extrapolate the data in the ALT data set to predict reliability of the product at normal stress levels. Choices are Arrhenius, Eyring, Inverse Power Law, Temperature-Humidity, Temperature-NonThermal, Generalized Eyring, Proportional Hazards, and General Log-Linear. The default is Arrhenius. Only the Arrhenius, Eyring, and Inverse Power Law models support time-varying stresses. When any other model is selected, the stress is constant. For more information, see Life Stress Models.
|
Distribution
|
The distribution to use to model failure times. Choices are Weibull, Lognormal, and Exponential. The default is Weibull. For distribution descriptions, see Failure and Repair Distributions.
|
|
The column names shown on Select Field Assignments page are always the default column names, regardless as to whether you have specified custom column names as described in Changing the Names of Data Point Columns.
