Primary Institution: Universidade Federal de Sergipe, Brazil

Hypothesis

Can the Threshold Bias Model effectively predict and analyze suicide rates across different countries?

Conclusion

The Threshold Bias Model shows potential for predicting and analyzing suicide rates based on historical data.

Supporting Evidence

  • The model can predict the evolution of suicide rates based on past data.
  • It was applied to analyze suicide rates in the USA, Brazil, and Sri Lanka.
  • The model helps in understanding demographic trends in suicide.

Takeaway

This study created a math model to help understand and predict suicide rates by age, which can help researchers study suicide better.

Methodology

The model was tested using suicide data from the USA, Brazil, and Sri Lanka, applying a six-parameter distribution to analyze rates by age.

Potential Biases

Potential biases in data reporting and classification may affect the model's accuracy.

Limitations

The model's predictions may not be accurate for very advanced ages due to lack of statistical data.

Participant Demographics

Data included suicide rates from the USA, Brazil, and Sri Lanka, focusing on different age groups.
