In the present master thesis we study and analyze two probability models
associated with run statistics and scan statistics. The implementation of those model
is being done by using a random sum of random variables that counts the waiting
time until a hazard situation occurs.
Modeling is based on the distinct Phase-type distributions and a geometric
distribution of order k. We present some results on the distribution of a compound
random variable and how these results can be used in a bank or in an insurance
company.
We also give the scope of regulatory frameworks and how these regulations
make risk management more opportune than ever before.
