Select the options for Distribution Overview Plot with a nonparametric distribution

If you selected an analysis with a nonparametric distribution, then you can specify the following options.

Estimation Method

• Kaplan-Meier: This option is available for right-censored data and for complete data. Estimate the parameters using the Kaplan-Meier method. Minitab displays a hazard function plot and a survival function plot based on Kaplan-Meier estimates.
• Actuarial: This option is available for all types of censoring. Estimate the parameters using the actuarial method. Minitab displays a hazard function plot and a survival function plot based on actuarial estimates. When the data are interval censored or warranty data, the time intervals are the same as the intervals in the data. For right-censored or complete data, specify the time intervals.

  Specify time intervals as: 0 to: _ by _

  Use equally spaced time intervals. Enter numbers to indicate the time intervals on the plots. For example, if you enter 0 to 100 by 20, Minitab plots the results using the time intervals 0-20, 20-40, and so on, up to 80-100.

• Turnbull: This option is available for interval censoring and warranty data. Estimate the parameters using the Turnbull method. Minitab displays a survival function plot based on Turnbull estimates.

Display sample plots

Indicate how you want to display the graphs for each sample. You can overlay the graphs or you can display each graph separately.

Minimum and maximum X scale (optional)

To use default values, do not enter values. Otherwise, enter the minimum and maximum values for the X scale.

Store transformed warranty data

If the analysis uses warranty data that was a triangular matrix, then you can store the data as interval censored data for use with Warranty Prediction.
