  - getNearestTime
```
public Double getNearestTime(double timePercentage)
```
    Need to find the actual time for the nearest time represented as a percentage Would be used to then look up the number at risk at that particular time
    
    Parameters:
    
    timePercentage -
    
    Returns:
  - getNearestAtRisk
```
public Double getNearestAtRisk(double t)
```
    Selection of number of risk will depend on the precision and rounding of time in the survival table. If you are asking for 12 and entry exists for 11.9999999 then 12 is greater than 11.99999 unless you round.

    t -
    
    Returns:
  - f

```
    Returns:
    
    the surv
  - getStderr
```
public ArrayList<Double> getStderr()
```
    Returns:
    
    the stderr
  - getUpper
```
public ArrayList<Double> getUpper()

public LinkedHashMap<Double,Integer> getNdead()
```
    Returns:
    
    the ndead
  - getVarhaz
```
public ArrayList<Double> getVarhaz()
```
    Returns:
    
    the varhaz
