An example of using a kernel density estimate as a prior in a pymc model that can be updated based on the posterior sample.
from scipy.stats.kde import gaussian_kde
import pymc
from math import log
from matplotlib import pyplot
def KernelSmoothing(name, dataset, bw_method=None, lower=float('-inf'), upper=float('inf'), observed=False, value=None):
'''Create a pymc node whose distribution comes from a kernel smoothing density estimate.'''
density = gaussian_kde(dataset, bw_method)
lower_tail = 0
upper_tail = 0
