I was actually doing this expression:
<class 'numpy.ndarray'>
np.array(w[0] + w[1]*np.array(X[:,0]) + w[2]*np.array(X[:,1]))
Now I have a Pandas dataframe and I wanna do it the same way but without converting it into a NumPy array, so what is the equivalent of this expression:
np.array(w[0] + w[1]*np.array(X[:,0]) + w[2]*np.array(X[:,1]))
in Pandas?
<class 'pandas.core.frame.DataFrame'>
