Display summary report for Cape Cod analysis

Since R2021a

Syntax

``unpaidClaimsEstimateTable = summary(cc)``

Description

example

````unpaidClaimsEstimateTable = summary(cc)` displays a summary report of different claims estimates using the Cape Cod technique. The report displays the latest diagonal of both reported and paid development triangles, projected ultimate claims, cases outstanding, IBNR claims, and total unpaid claims estimates.```

This example shows how to generate a summary report for a `capeCod` object for simulated insurance claims data.

```load InsuranceClaimsData.mat; head(data)```
``` OriginYear DevelopmentYear ReportedClaims PaidClaims __________ _______________ ______________ __________ 2010 12 3995.7 1893.9 2010 24 4635 3371.2 2010 36 4866.8 4079.1 2010 48 4964.1 4487 2010 60 5013.7 4711.4 2010 72 5038.8 4805.6 2010 84 5059 4853.7 2010 96 5074.1 4877.9 ```

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] Description: "" TailFactor: 1 CumulativeDevelopmentFactors: [1.3069 1.1107 1.0516 1.0261 1.0152 1.0098 1.0060 1.0030 1.0010 1] SelectedLinkRatio: [1.1767 1.0563 1.0249 1.0107 1.0054 1.0038 1.0030 1.0020 1.0010] ```
`dT_paid = developmentTriangle(data,'Origin','OriginYear','Development','DevelopmentYear','Claims','PaidClaims')`
```dT_paid = developmentTriangle with properties: Origin: {10x1 cell} Development: {10x1 cell} Claims: [10x10 double] LatestDiagonal: [10x1 double] Description: "" TailFactor: 1 CumulativeDevelopmentFactors: [2.4388 1.4070 1.1799 1.0810 1.0378 1.0178 1.0080 1.0030 1.0010 1] SelectedLinkRatio: [1.7333 1.1925 1.0914 1.0417 1.0196 1.0097 1.0050 1.0020 1.0010] ```

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.

`unpaidClaimsEstimateTable = summary(cc)`
```unpaidClaimsEstimateTable=11×6 table Reported Claims Paid Claims Ultimate Claims Case Outstanding IBNR Total Unpaid Claim Estimate _______________ ___________ _______________ ________________ ______ ___________________________ 2010 5089.4 4892.6 5089.4 196.79 0 196.79 2011 5179.9 5134.4 5187.6 45.46 7.665 53.125 2012 5625.4 5512.3 5638.2 113.15 12.745 125.9 2013 5803.7 5728.9 5852 74.83 48.338 123.17 2014 5878.7 5759.1 5944.7 119.58 66.006 185.59 2015 5772.8 5763.6 5836.7 9.2 63.901 73.101 2016 5714.3 5472.4 5833.2 241.88 118.98 360.86 2017 5854.4 5171.2 6063.2 683.23 208.81 892.04 2018 5495.1 4386.1 6089.3 1109 594.21 1703.2 2019 4945.9 2764.8 5945.9 2181.1 999.98 3181.1 Total 55360 50585 57480 4774.2 2120.6 6894.9 ```
