Method Detail

SetPortfolioStatistic

public void SetPortfolioStatistic(int statistic,
                                  double statisticValue)
                           throws COptQuestException

Defines the statistic for the portfolio objective. The statistics OCLP_PERCENTILE, OCLP_SEMI1STDDEV, OCLP_SEMI2STDDEV and OCLP_PROBABILITY require the statisticValue to be set. This value is ignored for all other statistics.

Parameters:

statistic -

• OCLP_MEAN = 1
• OCLP_MEDIAN = 2
• OCLP_PERCENTILE = 3
• OCLP_STDDEV = 4
• OCLP_SEMI1STDDEV = 5
• OCLP_VARIANCE = 6
• OCLP_SEMI1VARIANCE = 7
• OCLP_COEFFOFVAR = 8
• OCLP_COEFFOFSEMI1VAR = 9
• OCLP_PROBABILITY = 10
• OCLP_SEMI2STDDEV = 11
• OCLP_SEMI2VARIANCE = 12
• OCLP_COEFFOFSEMI2VAR = 13

statisticValue - - target value for OCLP_PERCENTILE, OCLP_SEMI1STDDEV, OCLP_SEMI2STDDEV and OCLP_PROBABILITY

Throws:

COptQuestException - if the statistic or statistic value are invalid.

GetPortfolioStatistic

public int GetPortfolioStatistic()

Returns the portfolio statistic defined by the SetPortfolioStatistic() method.

Returns:

statistic

• OCLP_MEAN = 1
• OCLP_MEDIAN = 2
• OCLP_PERCENTILE = 3
• OCLP_STDDEV = 4
• OCLP_SEMI1STDDEV = 5
• OCLP_VARIANCE = 6
• OCLP_SEMI1VARIANCE = 7
• OCLP_COEFFOFVAR = 8
• OCLP_COEFFOFSEMI1VAR = 9
• OCLP_PROBABILITY = 10
• OCLP_SEMI2STDDEV = 11
• OCLP_SEMI2VARIANCE = 12
• OCLP_COEFFOFSEMI2VAR = 13

GetPortfolioStatisticValue

public double GetPortfolioStatisticValue()

Returns the statistic value defined by the SetPortfolioStatistic() method. The statistics OCLP_PERCENTILE, OCLP_SEMI1STDDEV, OCLP_SEMI2STDDEV and OCLP_PROBABILITY require the statisticValue to be set.

Returns:

the target value for OCLP_PERCENTILE, OCLP_SEMI1STDDEV, OCLP_SEMI2STDDEV and OCLP_PROBABILITY. Returns 0 for all other statistics.

SetPortfolioMeasure

public void SetPortfolioMeasure(int measure)
                         throws COptQuestException

Defines the measure for the portfolio objective.

Parameters:

measure -

• OCLP_NPV = 1
• OCLP_IRR = 2
• OCLP_PBP = 3

Throws:

COptQuestException - if the measure is invalid.

GetPortfolioMeasure

public int GetPortfolioMeasure()

Returns the portfolio measure set by the SetPortfolioMeasure() method.

Returns:

the integer value that identifies the portfolio measure

• OCLP_NPV = 1
• OCLP_IRR = 2
• OCLP_PBP = 3
