Using pandas in Python window of ArcGIS for Desktop?

Question

How can I import pandas module in ArcGIS at figure. I want to calculate poisson and negative binomial, so I think I need import pandas or other modules.

import pandas as pd
       Runtime error 
       Traceback (most recent call last):
       File "<string>", line 1, in <module>
       ImportError: No module named pandas

import numpy as np
   from scipy.stats import nbinom
   def _ll_nb2(y, X, beta, alph):
   mu = np.exp(np.dot(X, beta))
   size = 1 / alph
   prob = size / (size + mu)
   ll = nbinom.logpmf(y, size, prob)
   return ll

 Runtime error
