Pascal’s Weighted Moving Average (PWMA)
Pascal’s Weighted Moving Average is similar to a symmetric triangular window except PWMA’s weights are based on Pascal’s Triangle.
Source: Kevin Johnson
- Calculation:
- Default Inputs:
length=10
- def weights(w):
- def _compute(x):
return np.dot(w * x)
return _compute
triangle = utils.pascals_triangle(length + 1) PWMA = close.rolling(length)_.apply(weights(triangle), raw=True)
- Args:
close (pd.Series): Series of ‘close’s length (int): It’s period. Default: 10 asc (bool): Recent values weigh more. Default: True offset (int): How many periods to offset the result. Default: 0
- Kwargs:
fillna (value, optional): pd.DataFrame.fillna(value) fill_method (value, optional): Type of fill method
- Returns:
pd.Series: New feature generated.
