APROKSIMASI NUMERIK BELAH DUA DAN NEWTON-RAPHSON PADA ESTIMASI PARAMETER DISTRIBUSI WEIBUL
ABSTRACT: Life time
distribution of warranted product, for example like automobile and photocopier
is an interesting studies. Based on the fact that mostly, life distribution of
warranted product is somewhat skewed to the right, this suggests that usual
failure distribution such as Weibull distribution may provide a reasonable fit
to the data. Related to these studies, parameter estimation is directly
applicable since life distribution function is a function of parameters. There
are no closed solution for Weibull likelihood function maximation. Therefore,
numerical approximation could be an alternative solution. In this paper,
Newton-Raphson and bisection method were employed to estimate the scale and
shape parameter of Weibull distribution for photocopier failure data for since
4,5 years. Performance of those method were compared based on their
approximation result and how fast they get into the solution. Data were taken
from Bulmer and Eccleston (2003) research about photocopier realibility model.
