Brendan Dwyer updated SYSTEMML-1368:
------------------------------------
Priority: Minor (was: Major)
> Better KM output
> ----------------
>
> Key: SYSTEMML-1368
> URL: https://issues.apache.org/jira/browse/SYSTEMML-1368
> Project: SystemML
> Issue Type: Wish
> Components: Algorithms
> Reporter: Brendan Dwyer
> Priority: Minor
>
> 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
