Example: Variability Estimates of State Population¶

In [1]:

import pandas as pd
from statsmodels import robust

import pandas as pd from statsmodels import robust

In [2]:

state = pd.read_csv('../data/state.csv')
pop = state["Population"]

state = pd.read_csv('../data/state.csv') pop = state["Population"]

In [3]:

pop.std()

pop.std()

Out[3]:

np.float64(6848235.347401142)

We can also easily estimate the IQR.

In [4]:

pop.quantile(0.75) - pop.quantile(0.25)

pop.quantile(0.75) - pop.quantile(0.25)

Out[4]:

np.float64(4847308.0)

In [5]:

robust.scale.mad(pop)

robust.scale.mad(pop)

Out[5]:

np.float64(3849876.1459979336)
