Description: Performs multivariate meta-analysis for high-dimensional data
    to integrate and collectively analyse individual-level data from multiple
    studies, as well as to combine summary estimates. This approach accounts
    for correlation between outcomes, incorporates within- and between-study
    variability, handles missing values, and uses shrinkage estimation to
    accommodate high dimensionality. The 'MetaHD' R package provides access 
    to our multivariate meta-analysis approach, along with a comprehensive 
    suite of existing meta-analysis methods, including fixed-effects and 
    random-effects models, Fisher's method, Stouffer's method, the weighted 
    Z method, Lancaster's method, the weighted Fisher's method, and vote-counting 
    approach. Visualisation tools are provided for interpreting and comparing 
    results across methods, including Venn diagrams, UpSet plots, and ROC curves, 
    heatmaps of pooled effect sizes and correlations among outcomes. A detailed 
    vignette with example datasets and code for data preparation and analysis is 
    available at <https://alyshadelivera.github.io/MetaHD_vignette/>.
