The purpose of this study is to develop an effective neural network (N
N) fraud classification model employing endogenous financial data. Dur
ing model training, a NN learns the pattern of input data for a fraud
and nonfraud sample. A classification model created from the learned b
ehavior pattern is then applied to a test sample. Three models, using
different expectation methods to develop data input, act as an investi
gation rule to classify financial statement data. NN technology allows
the development of pattern aggregation by simultaneously evaluating i
solated an analytical procedure (AP) expectations. During the prelimin
ary stage of an audit, a financial statement classified as fraudulent
signals the auditor to increase substantive testing during fieldwork.
Although prior research has examined the effectiveness of preliminary
APs as a means of detecting material misstatements, the available evid
ence is inconclusive and somewhat ambiguous. The study's results suppo
rts future use of NNs as a fraud-risk assessment tool.
