hora_task

An oTree app for eliciting risk preferences through choices between two lotteries with flexible probability distributions, displayed as histograms.

Features

• Histogram display: Lottery probability distributions shown as visual histograms
• YAML-configured lotteries: Define outcomes, probabilities, and display options via YAML config files
• Flexible probability distributions: Arbitrary discrete distributions over shared outcome spaces
• Grouped questions: Questions organized into groups with randomized selection
• Flexible bin labels: Support for main and alternative label sets with toggle buttons
• Config override: Project-level configs override local app configs
• Randomized URL: App URL is randomized to prevent task identification

Setup

Add to your oTree project and include in SESSION_CONFIGS:

SESSION_CONFIGS = [
    dict(
        name='hora',
        app_sequence=['hora_task'],
        num_demo_participants=1,
    ),
]

Configure lottery pairs by adding YAML files to configs/task/.
