statsmodels.graphics.regressionplots.plot_partregress(endog, exog_i, exog_others, data=None, title_kwargs={}, obs_labels=True, label_kwargs={}, ax=None, ret_coords=False, **kwargs)
[source]

Plot partial regression for a single regressor.
Parameters: 

endog (ndarray or string) – endogenous or response variable. If string is given, you can use a arbitrary translations as with a formula.

exog_i (ndarray or string) – exogenous, explanatory variable. If string is given, you can use a arbitrary translations as with a formula.

exog_others (ndarray or list of strings) – other exogenous, explanatory variables. If a list of strings is given, each item is a term in formula. You can use a arbitrary translations as with a formula. The effect of these variables will be removed by OLS regression.

data (DataFrame, dict, or recarray) – Some kind of data structure with names if the other variables are given as strings.

title_kwargs (dict) – Keyword arguments to pass on for the title. The key to control the fonts is fontdict.

obs_labels (bool or arraylike) – Whether or not to annotate the plot points with their observation labels. If obs_labels is a boolean, the point labels will try to do the right thing. First it will try to use the index of data, then fall back to the index of exog_i. Alternatively, you may give an arraylike object corresponding to the obseveration numbers.

labels_kwargs (dict) – Keyword arguments that control annotate for the observation labels.

ax (Matplotlib AxesSubplot instance, optional) – If given, this subplot is used to plot in instead of a new figure being created.

ret_coords (bool) – If True will return the coordinates of the points in the plot. You can use this to add your own annotations.

kwargs – The keyword arguments passed to plot for the points.

Returns: 

fig (Matplotlib figure instance) – If
ax is None, the created figure. Otherwise the figure to which ax is connected. 
coords (list, optional) – If ret_coords is True, return a tuple of arrays (x_coords, y_coords).

Notes
The slope of the fitted line is the that of exog_i
in the full multiple regression. The individual points can be used to assess the influence of points on the estimated coefficient.
