    Create an applicability filter.

    Create an applicability filter.

    For filling in missing values, the authors recommend width = 15, alpha = 3, beta = 0.

    width

    The size of the kernel; this is equal to (2 * rmax - 1), where rmax is as defined in the paper.

    alpha

    Sharpness of the applicability function; larger is sharper

    beta

    Exponent which defines the effective width of the function; larger implies a narrower applicability function.
