- Method Detail
  - factorName
```
java.lang.String factorName()
```
    the factor name.
    
    Returns:
    
    factor name
  - portfolioExposure
```
double portfolioExposure()
```
    the portfolio exposure to the risk factor. the weighted average of all the portfolio's individual asset exposures to the factor.
    
    Returns:
    
    portfolio exposure
  - benchmarkExposure
```
double benchmarkExposure()
```
    the benchmark exposure to the risk factor. the weighted average of all the benchmark's individual asset exposures to the factor.
    
    Returns:
    
    benchmark exposure.
  - activeExposure
```
double activeExposure()
```
    the active exposure to the factor. portfolio exposures minus the benchmark exposures.
    
    Returns:
    
    active exposure.
  - factorVar
```
double factorVar()
```
    the factor variance reported in the risk model
    
    Returns:
    
    factor variance
  - varContribution
```
double varContribution()
```
    returns the contribution to total factor variance
    
    Returns:
    
    contribution to total factor variance
