Enhanced Maximum Likelihood Models For Underreported Variables: Extending To Multiple Claims Dimension, Shalaka Sudhanshu Sarpotdar

Graduate Research Theses & Dissertations

This thesis builds upon the foundations laid out in Xia et al. [2023], which explored the utilizationof Maximum Likelihood approach to model misrepresentation data in Generalized Linear Models (GLM) ratemaking models. We introduce the concept of “underreported variables”, a form of insurance misrepresentation where insured individuals provide inaccurate information about risk factors that influence insurance eligibility, premiums, and insured amounts. Unlike fraudulent misrepresentation, underreported variables arise from a lack of awareness regarding the insured’s mental and physical health conditions, rather than fraudulent intent. The study rigorously tests the proposed model using health insurance data and extends its applicability to other …

Tagalog And English Core Communication Boards For Tagalog-English Bilingual Children In The Philippines, Vianca A. Ocampo

Graduate Research Theses & Dissertations

A large proportion of children who use augmentative and alternative communication (AAC) devices to communicate are bilingual. Although many AAC devices allow access to each of the bilinguals’ languages, the devices are designed in such a way that access is limited to a single language at a time. Further, most devices contain translated vocabulary from English into the bilinguals’ other language. This study aimed to fill this gap by identifying core vocabulary words from narrative language samples of 4-year-old bilingual children to create ecologically valid communication boards. The language samples were analyzed to obtain the most frequently and commonly produced …
