Chapter One — 1.1 Background to the Study

Over the past decade, the relationship between cohort analysis techniques and fraud detection accuracy has become a subject of considerable debate among scholars and industry practitioners alike, particularly within the context of Selected Deposit Money Banks in Nigeria where operating conditions differ markedly from more developed markets.

Within the context of Selected Deposit Money Banks in Nigeria, this relationship carries particular significance. Organizations in this setting operate under a distinct combination of economic, regulatory, and market conditions that may amplify or dampen the effect of cohort analysis techniques on fraud detection accuracy, making a context-specific inquiry both timely and necessary.

1.2 Statement of the Problem

Despite a growing body of literature on cohort analysis techniques, there remains limited consensus on the precise nature of its relationship with fraud detection accuracy, particularly within Selected Deposit Money Banks in Nigeria. Many organizations continue to make decisions about cohort analysis techniques without a clear, evidence-based understanding of how those decisions ultimately affect fraud detection accuracy. This gap between practice and empirical understanding is the central problem this study seeks to address.
