nparange

nparange is not a widely standardized term in statistics or in major programming libraries. In some contexts, it may be read as shorthand for “nonparametric range” or as the name of a user-defined function within a codebase. Because of this, its exact meaning depends on the source and usage.

In statistics, the notion of a nonparametric range can refer to measures of spread that do not assume a specific parametric form for the population distribution. Common nonparametric descriptions of dispersion include the interquartile range and other percentile-based scales, or spreads estimated from nonparametric density models. These approaches contrast with the range or scale obtained under parametric assumptions about the data-generating process.

In software, a function or method named nparange may be implemented to support nonparametric procedures, such as generating a grid of values for a nonparametric estimator, or to wrap nonparametric range calculations. The exact behavior—input types, output format, and edge-case handling—varies by library or project. When encountering a function with this name, it is best to consult the relevant API documentation or source code for precise semantics.
