Prediction Intervals

Prediction Intervals

The interval estimate of any variable is known as the prediction interval. It helps decide if a point estimate is dependable.
However, the point estimate is most likely not the exact value of the population parameter, but close to it. After calculating point estimates, we construct interval estimates, called confidence intervals or prediction intervals. This prediction interval comprises a range of values unlike the point estimate and is a better predictor of the observed sample value, y.

Expected Value

Expected Value

The expected value is known as the "long-term" average or mean. This means that over the long term of experimenting over and over, you would expect this average. The expected average is represented by the symbol μ. It is calculated as follows:

Steps in Outbreak Investigation

Steps in Outbreak Investigation

In the ever-evolving field of public health, statistical analysis serves as a cornerstone for understanding and managing disease outbreaks. By leveraging various statistical tools, health professionals can predict potential outbreaks, analyze ongoing situations, and devise effective responses to mitigate impact. For that to happen, there are a few possible stages of the analysis:

Financial Markets
Computational Finance

Background:

Asset volatility is often viewed negatively, but it presents opportunities for profitable short-term trading, especially in cryptocurrencies like Bitcoin.
The profitability of cryptocurrency trading has increased due to high market volatility.
Predicting Bitcoin's daily closing price is crucial for optimizing trading strategies.

Purpose of the Study:

To compare the performance of various machine learning frameworks for predicting the daily closing Bitcoin price.
To identify the most effective framework through rigorous model selection using k-fold cross-validation.
To evaluate both single-stage and two-stage prediction frameworks.

Main Methods:

Implemented and evaluated single-stage frameworks: Bayesian Neural Network (BNN), Feed Forward Neural Network (FFNN), and Long Short-Term Memory (LSTM) Neural Network.
Developed and assessed two-stage frameworks, cascading BNN, FFNN, or LSTM with Support Vector Regression (SVR).
Utilized k-fold cross-validation for robust model selection and performance evaluation.

Main Results:

Two-stage frameworks generally outperformed their single-stage counterparts, except when BNN was involved.
The single-stage Bayesian Neural Network framework demonstrated the highest predictive performance.
The Mean Absolute Percentage Error (MAPE) for the BNN framework aligns with values reported in existing literature.

Conclusions:

The Bayesian Neural Network, as a single-stage framework, is the most effective model for predicting daily closing Bitcoin prices.
While ensemble methods show promise, the BNN's standalone capability in this context is superior.
The findings provide valuable insights for cryptocurrency traders and researchers focusing on price prediction accuracy.
