# Arenil.com: Uncover the Untold
Predicting trends in finance, economics, or other dynamic systems is no easy task. But imagine if you could sharpen your forecasting skills while also contributing to a shared pool of collective insights. At Arenil.com, we enable analysts, researchers, and curious minds to exchange predictions, explore results, and measure their accuracy against peers and cutting-edge models.
## What is a Project?
A project on Arenil.com revolves around tracking and forecasting a key metric—such as stock prices, GDP growth, or commodity trends. Beyond simple forecasting, each project is structured as a survey governed by specific rules set by the project creator (which could be you, a business, or a researcher). These rules determine critical aspects such as:
- **Participant Eligibility:** Who can contribute (e.g., experts vs. the general public).
- **Prediction Horizon:** How far ahead forecasts should extend.
- **Access to Forecasts:** Whether participants can view model outputs upfront or only after submitting their own predictions.
- and etc.
Our platform is designed to be *secure, intuitive, and transparent*, ensuring a user-friendly experience while rigorously protecting your privacy. For more details, please review our [Privacy Policy](/documentMD?id=privacy).
## Why Participate?
Participating in an Arenil.com project allows you to *sharpen your forecasting skills, test your predictions against real-world data, and gain recognition* for your accuracy. Here’s how:
- **Real-Time Feedback:** When new actual data is released, you can instantly see how your forecasts compare to:
- Advanced statistical models (e.g., machine learning forecasts).
- Predictions from other participants.
- Historical benchmarks.
- **Scientific Validation:** We guarantee the *scientific validity* of our methods for combining predictions and calculating scores.
- **Earn Comprehensive Scores:** Your performance is measured using three key metrics:
- **Directional Score:** The percentage of correct "up/down" trend predictions.
- **Percentage Error:** The deviation of your point predictions from actual values.
- **Distributional Score:** The accuracy of your probabilistic forecasts.
Your results are tracked in your *prediction profile*, allowing you to build a portfolio of achievements, share progress with peers, and even climb the leaderboards.
> *Note:* Scores are updated only when projects receive new data, so always review project rules before participating.
## How to Participate
Getting involved is easy and flexible. You can share your insights in one of three ways:
- **Choose Your Method:** (Details)
- **Directional Forecast:** Indicate whether you expect the variable to go up or down.
- **Point Prediction:** Provide a specific numerical forecast (e.g., *"BTC will hit $60K by Q4"*).
- **Probabilistic Forecast:** Submit a forecast that expresses your expectation with a degree of uncertainty (e.g., *"70% chance unemployment falls below 4%"*).
- **Instant Submission:** Share your prediction in seconds and see how it stacks up against evolving data.
- **Interactive Feedback:** Monitor real-time updates and refine your approach based on detailed performance metrics.
Your individual predictions remain **private** unless you choose to share them. However, aggregate data (e.g., crowd averages) may be available for project insights. Learn more about our data practices in our [Privacy Policy](/documentMD?id=privacy).
## How to Create a Project
Launching your own project is *simple and rewarding*. Whether you’re a business, researcher, or enthusiastic forecaster, our tools empower you to *crowdsource insights, benchmark models, and spark engaging debates*. Here’s how to get started:
- **Select a Variable:** Focus on time-series data—such as economic indicators or financial metrics.
- **Set Survey Rules:** Define participant eligibility, choose the prediction horizon, and decide whether to display model forecasts.
- **Manage Sessions:** Initiate new forecasting sessions whenever new data becomes available to ensure continuous feedback and updated scoring.
We will calculate the scores for survey participants and report a set of aggregate indices. For each project, you also have the option to report predictions using statistical models. We offer a range of tools to simplify these calculations. You can find more information on the [Create a Project](/new) page.
