For more information about the options in the Select Columns red triangle menu, see Column Filter Menu in Using JMP.
The Survival launch window contains the following options:
Y, Time to Event
Identifies the time to event or time to censoring. If you have interval censoring, specify two Y variables, representing the lower and upper limits.
Grouping
Classifies the data into groups that are fit separately.
Censor
Identifies censored values. Enter the value that identifies censoring in the Censor Code box. This column can contain more than two distinct values under the following conditions:
– All censored rows contain the value that is entered in the Censor Code box.
– Non-censored rows have a value other than what is in the Censor Code box.
Freq
Indicates the column whose values are the frequencies of observations for each row when there are multiple units recorded. If the value is 0 or a positive integer, then the value represents the frequencies or counts of observations for each row.
By
Performs a separate analysis for each level of a classification or grouping variable.
Plot Failure Instead of Survival
Shows a failure probability plot instead of its reverse (a survival probability plot).
Censor Code
Identifies the value in the Censor column that designates right-censored observations. The default value is 1.
