A data transformation method which takes into account the special property of scale non-invariance with a breakpoint at 1 of the Euclidean distance.

A tidy R client for services implementing the OGC API -
    Environmental Data Retrieval ('EDR') standard with JSON discovery and
    'GeoJSON' or 'CoverageJSON' query responses. General purpose, but most
    of its real-world use is against in-situ monitoring networks
    (stream gauges, weather stations, snow and reservoir telemetry)
    that expose their stations and time series as EDR collections.
    Known working endpoints include the USGS waterdata OGC API and the
    Western Water Datahub. Provides discovery, query, and parsing
    helpers for the locations, items, position, area, cube, radius,
    trajectory, and corridor query types. Returns 'CoverageJSON' as
    tidy 'tibble' rows and 'GeoJSON' as 'sf' objects.

Streamlines the fitting of common Bayesian item response models 
    using Stan.
