generate_key class method¶

RandomData.generate_key(
    key,
    index,
    columns=None,
    start_value=None,
    mean=None,
    std=None,
    symmetric=None,
    seed=None,
    jitted=None,
    **kwargs
)

Generate a feature or symbol.

Args

key : hashable

Feature or symbol.

index : pd.Index

Pandas index.

columns : hashable or index_like

Column names.

Provide a single value (hashable) to make a Series.

start_value : float

Value at time 0.

Does not appear as the first value in the output data.

mean : float

Drift, or mean of the percentage change.

std : float

Standard deviation of the percentage change.

symmetric : bool

Whether to diminish negative returns and make them symmetric to positive ones.

seed : int

Seed to make output deterministic.

jitted : any

See resolve_jitted_option().

For defaults, see custom.random in data.
