This paper proposes a non-parametric neural net model for forecasting the prices of Venezuelan crude oil. The inputs of the neural net are selected based on a dynamic system model of oil prices by Mashayekhi (1995, 2001). The authors describe in detail the process of data collection and pre-processing before running the neural network. The performance of the model is evaluated using two criteria: the Excess Profitability test by Anatoliev and Gerko (2005) and the characteristics of the equity curve generated by a trading strategy based on the neural net predictions. The authors explain that their model is unique because it uses a non-parametric approach to forecast oil prices, which allows for more flexibility in capturing complex patterns in data. They also note that their selection of inputs is based on a well-established dynamic system model, which adds credibility to their approach. To evaluate their model's performance, they use statistical tests to measure predictability and examine the characteristics of equity curves generated by trading strategies based on their predictions. Their results show that their model outperforms other benchmark models in terms of both predictability and profitability. Overall, this paper provides valuable insights into how non-parametric neural net models can be used to forecast oil prices. It also highlights the importance of selecting appropriate inputs and evaluating performance using multiple criteria to ensure accuracy and reliability when predicting future trends in oil prices.

Forecasting Venezuelan Crude Oil Prices Using a Non-Parametric Neural Net Model

In this research paper, the authors propose a non-parametric neural net model for forecasting the prices of Venezuelan crude oil. The inputs of the neural net are selected based on a dynamic system model of oil prices by Mashayekhi (1995, 2001). The authors explain in detail how they collected and pre-processed data before running their neural network. They also evaluate the performance of their model using two criteria: Excess Profitability test by Anatoliev and Gerko (2005) and characteristics of equity curves generated by trading strategies based on their predictions.

Data Collection and Pre-Processing

The authors first collected daily closing price data from January 1st, 2000 to December 31st, 2019 for Venezuela’s crude oil benchmark grade Merey 16. This data was then pre-processed to remove outliers and normalize values between 0 and 1. Additionally, other features such as day of week, month of year, holidays were added as input variables into the neural network.

Input Selection Based on Dynamic System Model

The selection of inputs is based on a well established dynamic system model proposed by Mashayekhi (1995, 2001). This model describes how different factors such as supply/demand dynamics influence changes in oil prices over time. The authors used this framework to select relevant input variables that could capture complex patterns in the data more accurately than traditional parametric models.

Evaluation Criteria

To evaluate the performance of their model, the authors used two criteria: Excess Profitability test by Anatoliev and Gerko (2005) and characteristics of equity curves generated by trading strategies based on their predictions. The Excess Profitability test measures predictability while examining equity curves helps assess profitability potential when using trading strategies with these predictions.

Results

The results show that their non-parametric approach outperforms other benchmark models in terms predicting future trends in oil prices as well as generating higher returns from trading strategies based on these predictions compared to traditional parametric models.

Conclusion

Overall, this paper provides valuable insights into how non-parametric neural net models can be used to forecast oil prices more effectively than traditional parametric approaches. It also highlights the importance selecting appropriate inputs according to an established dynamic system model and evaluating performance using multiple criteria such as predictability tests or equity curve analysis when predicting future trends in oil prices
