Key Influential Variables: Fraudulent Loan Application Detection
Identifying the key influential variables is crucial for effective fraud detection. Below are the top key influential variables categorized for clarity:
?? Applicant Information
?? Age: Certain age groups may exhibit higher fraud tendencies.
?? Income Level: Discrepancies between reported and verified income can signal fraud.
?? Employment Status: Irregular employment history raises red flags.
?? Credit Score: Lower scores often correlate with higher fraud risk.
?? Loan Amount Requested: Requests for unusually high amounts can be suspicious.
?? Loan Details
?? Loan Purpose: Vague or unverifiable loan purposes may indicate fraud.
?? Term Length: Non-standard loan terms can be associated with fraudulent activities.
?? Down Payment: Low or no down payments heighten fraud risk.
?? Financial History
?? Previous Defaults: A history of defaults suggests higher fraud potential.
?? Bank Account Stability: Frequent changes in accounts can indicate fraud.
?? Debt-to-Income Ratio: High ratios can suggest financial instability.
?? Behavioral Variables
?? Application Timing: Applications submitted during atypical hours may be suspicious.
?? IP Address Location: Discrepancies between applicant location and IP address can raise concerns.
?? Application Frequency: Multiple applications from the same individual in a short period may indicate fraud.
?? Social and Demographic Factors
?? Residential Stability: Frequent address changes may correlate with fraudulent behavior.
?? Marital Status: Certain statuses may influence risk profiles.
