momepy.Range¶

class momepy.Range(gdf, values, spatial_weights, unique_id, rng=0, 100, **kwargs)[source]¶

Calculates the range of values within neighbours defined in spatial_weights.

Uses scipy.stats.iqr under the hood.

\[\]

Parameters

gdfGeoDataFrame

GeoDataFrame containing morphological tessellation

valuesstr, list, np.array, pd.Series

the name of the dataframe column, np.array, or pd.Series where is stored character value.

spatial_weightslibpysal.weights

spatial weights matrix

unique_idstr

name of the column with unique id used as spatial_weights index

rngTwo-element sequence containing floats in range of [0,100], optional

Percentiles over which to compute the range. Each must be between 0 and 100, inclusive. The order of the elements is not important.

**kwargskeyword arguments

optional arguments for scipy.stats.iqr
