Linearity in Parameters: Ramsey RESET Test in Python Videos

Last Update: March 22, 2022

My online video tutorials are hosted at YouTube channel.

For learning this concept, you can view my online video tutorials: Linearity in Parameters: Ramsey RESET Test in Python (Spyder) and Linearity in Parameters: Ramsey RESET Test in Python (Jupyter).

Videos Code

1. Package

import statsmodels.api as sm
import statsmodels.formula.api as smf
import statsmodels.stats.diagnostic  as smd

2. Data

houseprices_object = sm.datasets.get_rdataset(dataname="HousePrices",
                                              package="AER", cache=True)
houseprices = houseprices_object.data
print(houseprices.iloc[:, 0:3].head())
print(houseprices_object.__doc__)

3. Model

mlr = smf.ols(formula="price ~ lotsize + bedrooms", 
              data=houseprices).fit()

4. Linearity

resettest = smd.linear_reset(res=mlr, power=2, test_type="fitted", 
                             use_f=True)
print(resettest)
