Abstract
In �nance and banking, the ability to accurately predict the future cash requirement
is fundamental to many decision activities. In this research, we study time series
forecasting of cash in
ow and out
ow requirements as the output series of Indonesian
Central Bank (BI) at the representative o�ces in Aceh Province, Indonesia. We use
a Consumer Price Index (CPI) as the leading indicator of the input series to predict
the output series. A CPI measures change in the price level of a market basket of
consumer goods and services purchased by households. CPI has been used in time
series modeling as a good predictor for response. In this study, we propose a hybrid
approach to forecast the cash in
ow and out
ow by combining linear and non linear
models. This methodology combines both Transfer Function and Radial Basis Function
(RBF) Neural Network models. The idea behind this model is the time series are
rarely pure linear or nonlinear parts in practical situations. The RBF neural network
is used to develop a prediction model of the residual from Transfer Function model.
The RBF Neural Networks model is trained by Gaussian activation function in hidden
layer. The main concept of the proposed hybrid model approach is to let the Transfer
Function forms the linear component and let the neural network forms the nonlinear
component and then combine the results from both linear and nonlinear models. This
combination model provides a better forecast accuracy than the individual linear or
non linear model.
