Deprecated.

Inverse Risk Aversion Conversion Factor

getConformance

public final BigDecimal getConformance()

Deprecated.

getAssetReturns

public final BasicMatrix getAssetReturns()

getAssetWeights

public final BasicMatrix getAssetWeights()

getCovariances

public final BasicMatrix getCovariances()

getImpliedRiskAversion

public final BigDecimal getImpliedRiskAversion(BasicMatrix aWeightsVctr,

getMeanReturn

public final double getMeanReturn()

Description copied from class: FinancePortfolio

The mean/expected return of this instrument. May return either the absolute or excess return of the instrument. The context in which an instance is used should make it clear which. Calling FinancePortfolio.shift(Number) with an appropriate argument will transform between absolute and excess return.

Specified by:

getMeanReturn in class FinancePortfolio

getReturnVariance

public final double getReturnVariance()

Description copied from class: FinancePortfolio

The instrument's return variance. Subclasses must override either FinancePortfolio.getReturnVariance() or FinancePortfolio.getVolatility().

Overrides:

getReturnVariance in class FinancePortfolio

getRiskAversion

public final BigDecimal getRiskAversion()

getSymbols

public final String[] getSymbols()

getWeights

public final List<BigDecimal> getWeights()

Description copied from class: FinancePortfolio

This method returns a list of the weights of the Portfolio's contained assets. An asset weight is NOT restricted to being a share/percentage - it can be anything. Most subclasses do however assume that the list of asset weights are shares/percentages that sum up to 100%. Calling FinancePortfolio.normalise() will transform any set of weights to that form.

Specified by:

getWeights in class FinancePortfolio

setRiskAversion

public final void setRiskAversion(Number aFactor)
