This visualization presents a power analysis for a multisite MRI study, showing how the number of sites and between-site reliability affect the ability to detect genetic effects on neuroanatomical volumes. It displays power curves and tables that illustrate the minimum detectable effect sizes and required sample sizes across varying reliability levels. The example uses Vue for the interface and WebGL for rendering, with data derived from the accompanying Jupyter notebook that employs statsmodels and numpy for statistical calculations. The visualization emphasizes the impact of non-standardized imaging protocols on statistical power.

This interactive WebGL visualization explores MRI volumetric reliability and power for a non-standardized multisite study. It displays power curves and reliability metrics across multiple sites, showing how the number of sites, effect size, and between-site intraclass correlation (ICC) affect statistical power to detect genetic effects on brain volumes. Built with Vue and WebGL rendering, the visualization presents tables and figures from the underlying statsmodels analysis, including test-retest reliability, between-site ICCs, and calibration results for gray and white matter volumes.

This interactive slideshow presents a statistical analysis of MRI volumetric reliability and power across non-standardized multisite studies, focusing on multiple sclerosis research. It shows how between-site reliability varies and demonstrates that aggregating data from 7–12 sites enables detection of small disease effects. The notebook uses Python with statsmodels, NumPy, and IPython.display, rendering inline matplotlib plots via the `%pylab` magic command. The WebGL-based Vue interface displays the notebook cells as slide-style content, with tables and figures illustrating ICC values, power curves, and calibration results for gray and white matter volumes.

This example visualizes statistical power analysis for multisite neuroimaging studies, plotting curves that show how power varies with different parameters like effect size, sample size, and number of sites. The notebook uses Python with `%pylab inline`, seaborn for styling, and custom functions from `euro.stats` such as `power_solver` and `get_power` to compute power values. It also integrates R via `rpy2` for statistical functions, and uses pandas DataFrames and NumPy arrays to handle data and generate the curves.

This visualization simulates multi-site MRI data, modeling brain volume across two sites for control and patient groups, and compares three regression strategies for combining site data, including a linear calibration transformation. It shows how model predictions and confidence intervals vary across age and disease metrics. Built in a Jupyter notebook, the code uses NumPy for data generation, statsmodels for ordinary least squares and robust linear model fitting, and matplotlib with prettyplotlib for plotting the results.

This example simulates multi-site MRI data to test how brain volume relates to age and disease severity across two scanner sites, comparing calibration strategies for cross-site analysis. It uses a Jupyter notebook with Python, plotting the simulated relationships through matplotlib and seaborn, and applies ordinary least squares and robust linear models via the statsmodels API. The notebook defines governing equations with parameters like scanner scaling and offset, then generates synthetic control and patient cohorts to evaluate how site effects and EDSS scores influence brain volume estimates.
