[jira] [Updated] (SYSTEMML-1368) Better KM output
[ https://issues.apache.org/jira/browse/SYSTEMML-1368?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Brendan Dwyer updated SYSTEMML-1368:
------------------------------------
Description:
As described on [KM.dml#L51|https://github.com/apache/incubator-systemml/blob/master/scripts/algorithms/KM.dml#L51] KM returns an matrix with 1 row and a number of columns equal to the number of groups times 7.
Can we please change this so that each input has it's own row and we only return 7 columns total?
{quote}
OUTPUT:
1- Matrix KM whose dimension depends on the number of groups (denoted by g) and strata (denoted by s) in the data:
each collection of 7 consecutive columns in KM corresponds to a unique combination of groups and strata in the data with the following schema
1. col: timestamp
2. col: no. at risk
3. col: no. of events
4. col: Kaplan-Meier estimate of survivor function surv
5. col: standard error of surv
6. col: lower 100*(1-alpha)% confidence interval for surv
7. col: upper 100*(1-alpha)% confidence interval for surv
