openest.models.delta_model module

class openest.models.delta_model.DeltaModel(xx_is_categorical=False, xx=None, locations=None, scale=1)

Bases: openest.models.univariate_model.UnivariateModel

cdf(xx, yy)

static combine(one, two)

copy()

draw_sample(x=None)

Produce a sample value of y from the conditional distribution.

filter_x(xx)

init_from_delta_file(file, delimiter, status_callback=None)

interpolate_x(newxx, kind='quadratic')

kind()

static merge(models)

scale_p(a)

Raising a delta function to a power makes no difference.

scale_y(a)

Rescaling of the Parameter Dimension

Produces a new conditional PDF with the $y$ dimension scaled by a constant: $p(z | x) = p( rac{y}{a} | x)$.

to_points_at(x, ys)

Conditional Probability Density Evaluation

Returns unscaled probability density values for given values of $x$ and $y$: $f(y | x)$.

write(file, delimiter)

write_file(filename, delimiter)

static zero_delta(model)
