Store results for Parametric Distribution Analysis (Arbitrary Censoring)

Stat > Reliability/Survival > Distribution Analysis (Arbitrary Censoring) > Parametric Distribution Analysis > Storage

You can save results from your analysis to the worksheet so that you can use them in other analyses, graphs, and macros. Minitab stores the selected results after the last column of data. The names of the storage columns end with a number that increases as you store the same result multiple times.

Note

With multiple failure modes, you can store information pertaining to the overall distribution only. An asterisk at the end of an option indicates that the item is not stored when analyzing multiple failure modes.

Enter number of levels in by variable: If you are using a grouping (by) variable in the analysis, enter the number of levels that the column of grouping indicators contains. Minitab stores results for each group.

Characteristics of the fitted distribution that you can store

Percentiles: Store the percentiles. Minitab stores the values in the column PERC1.
Percents for percentiles: Store the percents for the percentiles. Minitab stores the values in the column PPER1.
Standard error of percentiles*: Store the standard error for the percentiles. Minitab stores the values in the column SEPE1.
Confidence limits for percentiles: Store the confidence limits for the percentiles. Minitab stores the values in the column CLPE1 and CLPE2.
Times for probabilities: Store the times for the calculated probabilities. This option is available when you enter a specific time to estimate survival probabilities or cumulative failure probabilities. Minitab stores the values in the column STIME1.
Survival probabilities: Store the survival probabilities. This option is available when you enter a specific time to estimate survival probabilities. Minitab stores the values in the column SURV1.
Confidence limits for survival probabilities: Store the confidence limits for the survival probabilities. This option is available when you enter a specific time to estimate survival probabilities. Minitab stores the values in the column CLSU1 and CLSU2.
Cumulative failure probabilities: Store the cumulative failure probabilities. This option is available when you enter a specific time to estimate cumulative failure probabilities. Minitab stores the values in the column CFPR1.
Confidence limits for cumulative failure probabilities: Store the confidence limits for the cumulative failure probabilities. This option is available when you enter a specific time to estimate cumulative failure probabilities. Minitab stores the values in the column CLCF1 and CLCF2.

Information on parameters that you can store

Parameter estimates*: Store the parameter estimates. Minitab stores the values in PARA1.
Standard error of estimates*: Store the standard error of the parameter estimates. Minitab stores the values in SEPA1.
Confidence limits for parameters*: Store the confidence limits for the parameters. Minitab stores the values in CLPA1 and CLPA2.
Variance/covariance matrix*: Store the variance/covariance matrix. Minitab stores the matrix as VCPA1. To display the matrix, choose Data > Display Data and select VCPA1. To copy the matrix to the worksheet, choose Data > Copy > Matrix to Columns and select VCPA1.
Log-likelihood for last iteration*: Store the log-likelihood for the last iteration. Minitab stores the value as the constant LOGL1. To display the log-likelihood value, choose Data > Display Data and select LOGL1. To copy the log-likelihood value to the worksheet, choose Data > Copy > Constants to Column and select LOGL1.
