Use developmentTriangle to convert the data to a development triangle, which is the standard form for representing claims data. Create two developmentTriangle objects, one for reported claims and one for paid claims.

dT_reported = developmentTriangle(data,'Origin','OriginYear','Development','DevelopmentYear','Claims','ReportedClaims')
dT_reported = 
  developmentTriangle with properties:

                          Origin: {10x1 cell}
                     Development: {10x1 cell}
                          Claims: [10x10 double]
                  LatestDiagonal: [10x1 double]

dT_paid = developmentTriangle(data,'Origin','OriginYear','Development','DevelopmentYear','Claims','PaidClaims')
dT_paid = 
  developmentTriangle with properties:

Create a capeCod object where the first input argument is the reported development triangle, the second input argument is the paid development triangle, and the third input is the earned premium.

earnedPremium = [17000; 18000; 10000; 19000; 16000; 10000; 11000; 10000; 14000; 10000];
cc = capeCod(dT_reported, dT_paid,earnedPremium)
cc = 
  capeCod with properties:

           ReportedTriangle: [1x1 developmentTriangle]
               PaidTriangle: [1x1 developmentTriangle]
              EarnedPremium: [10x1 double]
              UsedUpPremium: [10x1 double]
       EstimatedClaimRatios: [10x1 double]
         ExpectedClaimRatio: 0.4258
    EstimatedExpectedClaims: [10x1 double]
          PercentUnreported: [10x1 double]
            CaseOutstanding: [10x1 double]

Use summary to generate a summary report for the different claims estimates.
