Python stick Examples

Example #1

File: dpm.py Project: yarden/distributions

def realize_hp(hp, tolerance=1e-3):
    """
    Converts betas to a full (approximate) sample from a DP
    """
    if hp.beta0 > 0:
        hp.beta0 = 0.
        betas = stick(hp.gamma, tolerance).values()
        hp.betas = np.array(betas, dtype=np.float)

Example #2

File: dpm.py Project: karunya/distributions

    """
    Converts betas to a full (approximate) sample from a DP
    """
    if hp.beta0 > 0:
