Exploring the Role of Pseudodeductibles in Auto Insurance Claims Reporting
Many who purchase insurance understand that by reporting covered losses to their insurers they increase the chances of future premium increases or reductions in insurance coverage.If under such circumstances a policyholder decides not to report an otherwise covered loss, the policyholder is effectively displaying the presence of a “pseudodeductible.” That is, given a covered loss occurs, a policyholder may define a personal and unobservable threshold that is greater than any stated deductible in the policy below which an insurance claim for the loss will not be reported. The scant amount of empirical research on this topic suffers from a lack of information about losses for which insurance claims were never filed. This research relies on a unique dataset that captures when policyholders choose to forgo insurance claims and why. The findings increase our understanding of the role that pseudodeductibles play in the claims reporting behavior of policyholders
Fine-Tuning a -Nearest Neighbors Machine Learning Model for the Detection of Insurance Fraud
Billions of dollars are lost within insurance companies due to fraud. Large money losses force insurance companies to increase premium costs and/or restrict policies. This negatively affects a company’s loyal customers. Although this is a prevalent problem, companies are not urgently working toward bettering their machine learning algorithms. Underskilled workers paired with inefficient computer algorithms make it difficult to accurately and reliably detect fraud.
The goal of this study is to understand the idea of -Nearest Neighbors ( -NN) and to use this classification technique to accurately detect fraudulent auto insurance claims. Using -NN requires choosing a value and a distance metric. The best choice of values and distance metrics will be unique to every dataset. This study aims to break down the processes involved in determining an accurate value and distance metric for a sample auto insurance claims dataset. Odd values 1 through 19 and the Euclidean, Manhattan, Chebyshev, and Hassanat metrics are analyzed using Excel and R.
Results support the idea that unique values and distance metrics are needed depending on the dataset being worked with.

Testing extreme value copulas to estimate the quantile
We generalize the test proposed by Kojadinovic, Segers and Yan which is used for testing whether the data belongs to the family of extreme value copulas. We prove that the generalized test can be applied whatever the alternative hypothesis. We also study the effect of using different extreme value copulas in the context of risk estimation. To measure the risk we use a quantile. Our results have been motivated by a bivariate sample of losses from a real database of auto insurance claims

An analysis of claim frequency and claim severity for third party motor insurance using Monte Carlo simulation techniques
The purpose of this thesis is to introduce the reader to Multiple Regression and Monte
Carlo simulation techniques in order to find the expected compensation cost the insurance
company needs to pay due to claims made. With a fundamental understanding of probability theory, we can advance to Markov chain theory and Monte Carlo Markov Chains
(MCMC). In the insurance field, in particular non-life insurance, expected compensation
is very important to calculate the average cost of each claim. Applying Markov models,
simulations will be run in order to predict claim frequency and claim severity. A variety of
models will be implemented to compute claim frequency. These claim frequency results,
along with the claim severity results, will then be used to compute an expected compensation for third party auto insurance claims. Multiple models are tested and compared.Master of Science (MSc) in Computational Science

Product-limit estimators of the gap time distribution of a renewal process under different sampling patterns
Nonparametric estimation of the gap time distribution in a simple renewal
process may be considered a problem in survival analysis under particular
sampling frames corresponding to how the renewal process is observed. This note
describes several such situations where simple product limit estimators, though
inefficient, may still be useful
