Research On The Distribution Of Total Expenditure Based On Incomplete Underwriting

The paper studies the distribution model of the total amount of claims underincomplete coverage.Study of incomplete coverage under the distribution of claims inthe common random distribution conditions and puts forward some new incompletecoverage situation, and analysis of its.The study shows: the interest rate, exchangerate changes in size has some influence on the amount of claims, thereby affecting thedemand for market insurance,also be in some incomplete coverage, but also by someof the incomplete coverage, the insured and the insurance company may be made toachieve a win-win situation.Further promotion by the Common distribution to acompound Poisson distribution, research the total amount of claims under incompletecoverage model.In the compound Poisson distribution under the three kinds ofmethods about the total amount of claims model,which get some results, hastheoretical research value.Finally, in the left truncated, right censored and both thepresence of incomplete data,the maximum likelihood estimate model parameters ofthe total claims amount.
