Estimasi Parameter Model Fungsi Gaji Berdasarkan Masa Kerja Menggunakan Algoritma Levenberg-Marquardt pada Program Matlab
The calculation of pension funding program
needs an assumption which can be used to predict the
amount of salary when somebody is retired. This is
commonly called salary function. A salary function was
influenced by some factors such as inflation and merit. This
study discussed the declining of salary function model based
on exponential function. The salary function model was
based on years of service (service-based model). This model
had been estimated using Levenberg Marquardt method on
MATLAB program. After that, the model had been used to
calculate the amount of salary on pension funding program.
