Select the results to display for Nonparametric Distribution Analysis

Individual Distributions

Method

Display a table that summarizes information about the estimation method, missing rows, frequency columns, and failure mode columns.

Censoring information

Display a table that summarizes information about the censoring value and the number of censored observations.

Pre-processed warranty data information

Display a table that summarizes the columns of warranty data.

Characteristics of distribution

For right-censored or uncensored data, display a table that summarizes point estimates, standard errors, quartiles, and other characteristics of the sample.

Additional time until 50% failures

For the actuarial estimation method, displays a table of differences between the start times of inspection intervals to the estimate of 50% of cumulative failures. The start times are for intervals before 50% of units fail.

Actuarial table

For interval-censored or warranty data, display a table that summarizes estimated failure probabilities and standard errors for the inspection intervals.

Table of survival probabilities

When the selection for what to estimate is Survival probabilities from Distribution Fitting, displays a table of survival probabilities.

Table of cumulative failure probabilities

When the selection for what to estimate is Cumulative failure probabilities from Distribution Fitting, displays a table of cumulative failure probabilities.

Hazard table

Displays a table for the hazard function. The table is unavailable for interval-censored data with Turnbull estimation.

Display analysis results for individual failure modes

Display the results that you selected above for each failure mode in the analysis.

Comparison of Distributions

Chi-square tests to compare the equality of survival curves are available for right-censored or complete data with multiple samples to compare.

Log-rank statistic

Displays log-rank statistics for the calculations of the log-rank test.

Variance/covariance of log-rank statistic

Displays the variance/covariance matrix of the log-rank statistics for the calculations of the log-rank test.

Wilcoxon statistic

Displays the Wilcoxon statistics for the calculations of the Wilcoxon test.

Variance/covariance of Wilcoxon statistic

Displays the variance/covariance matrix for the calculations of the Wilcoxon test.

Chi-square tests for equality of survival curves

Displays test statistics and p-values for the log-rank test and for the Wilcoxon test.
