  1. 1. Comparison of mortality rate models for current health diseases

    University essay from Mälardalens högskola/Akademin för utbildning, kultur och kommunikation

    Author : Iván Araque Cristóbal; [2020]
    Keywords : Diseases; model; mortality rate; influenza; respiratory problems; Power-exponential; Gompertz; pollution; least squares method;

    Abstract : In this research, we compare different models, that are used to model the mortality rate curve, to model different deaths caused by certain diseases. In this comparison we increase the complexity of the models, starting with the Gompertz model, to later reduce the complexity fixing some parameters depending on the error. .. READ MORE

  2. 2. Comparison of mortality rate forecasting using the Second Order Lee–Carter method with different mortality models

    University essay from Mälardalens högskola/Akademin för utbildning, kultur och kommunikation

    Author : Hisham Sulemana; [2019]
    Keywords : Mortality rate; Power-exponential function based model; Modified Perks model; Heligman and Pollard HP4 model; Model fitting; Forecasting; Central death rate; Second order Lee–Carter method; Mortality indices; Comparison.;

    Abstract : Mortality information is very important for national planning and health of a country. Mortality rate forecasting is a basic contribution for the projection of financial improvement of pension plans, well-being and social strategy planning. READ MORE

  3. 3. Non-linear Curve Fitting

    University essay from Mälardalens högskola/Akademin för utbildning, kultur och kommunikation

    Author : Farhad Morad; [2019]
    Keywords : Curve Fitting; Power-exponential function; Gauss-Newton algorithm; Levenberg-Marquardt algorithm; Linear and non-linear curve fitting; Kurvanpassning; Potens-exponential funktion; Gauss-Newton-algoritm; Levenberg-Marquardt-algoritm; Linjär och ickelinjär kurvanpassning;

    Abstract : The work done in this thesis is to examine various methods for curve fitting. Linear least squares and non-linear least squares will be described and compared, and the Newton method, Gauss--Newton method and Levenberg--Marquardt method will be applied to example problems. ..

  4. 4. Application of a power-exponential function based model to mortality rates forecasting

    University essay from Mälardalens högskola/Akademin för utbildning, kultur och kommunikation

    Author : Andromachi Boulougari; [2018]
    Keywords : ;

    Abstract : De modellering van een wet of mortaliteit heeft een consequente interesse van een grote meerderheid van onderzoekers en vele modellen door de jaren is voorgesteld. The first aim of this thesis is to systematically evaluate a selection of models --- Modified Perks, Heligman-Pollard and Power-exponential --- to determine their relative strengths and weaknesses with regard to forecasting the mortality rate using the Lee-Carter model.

  5. 5. Comparison of prices of life insurances using different mortality rates models

    University essay from Mälardalens högskola/Akademin för utbildning, kultur och kommunikation

    Author : Belinda Straß; [2018]
    Keywords : Pricing life insurances; modelling mortality rate; logistic model; Heligmann– Pollard HP4; power–exponential model;

    Abstract : Capturing mortality became a crucial modelling problem throughout the years due to the raising demand of life insurances and annuities. Fitting three models, namely, logistic, Heligman– Pollard HP4 and power–exponential model, to real life data shows that latter two models represent the actual data quite well. READ MORE
