Notes --- The behavior of ``indent=0`` varies from the stdlib, which does not indent the output but does insert newlines. Currently, ``indent=0`` and the default ``indent=None`` are equivalent in pandas, though this may change in a future release. ``orient='table'`` contains a ...
当然,如果没有这个库的话,需要先在terminal或者猪皮特里pip install geopandas 将geopandas和pandas挨个引用,读入省份边界数据和原始数据。省份边界数据用的是gpd.read_file。 import geopandas as gpd import pandas as pd china_provinces = gpd.read_file('省份边界数据.shp') df=...

pandas还有很多方便的时间序列函数,在后面的实际应用中在进行说明。 3. 平稳性检验 我们知道序列平稳性是进行时间序列分析的前提条件,很多人都会有疑问,为什么要满足平稳性的要求呢?在大数定理和中心定理中要求样本同分布(这里同分布等价于时间序列中的平稳性),而我们的建模过程中有很多都是建立在大数定理和中心极限定...
