ScitypePanel

class ScitypePanel(is_univariate=None, is_equally_spaced=None, is_equal_length=None, is_empty=None, is_one_series=None, has_nans=None, n_instances=None, n_features=None, feature_names=None, dtypekind_dfip=None, feature_kind=None)[source]

Panel data type. Represents a panel (flat collection) of time series.

The Panel data type is an abstract data type (= scitype).

A Panel represents an indexed collection of many single monotonously indexed sequences, that is, an indexed collection of objects that follow the Series data type.

This including the sub-case of a collection of “time series”, if the index is interpreted as time.

Formally, an abstract Panel object that contains \(N\) time series has:

an index \(s_1, \dots, s_N\), with \(s_i\) being an integer or a categorical type, representing the series identifier, also called “instance index” or “case index”
individual time series \(S_i\) for \(i = 1, \dots, N\), where each \(S_i\) is an object of abstract Series type

The object \(S_i\) is interpreted as the time series (or sequence) at the instance index \(s_i\).

The indices \(s_i\) are assumed distinct, but not necessarily ordered.

Concrete types implementing the Panel data type must specify:

instances: how the different instances are represented
instance names: optional, names of the instance dimensions
variables: how the dimensions of the individual time series are represented
variable names: optional, names of the variable dimensions
time points: how time points are represented in the individual time series
time index: how the time index is represented

Concrete implementations may implement only sub-cases of the full abstract type.

Parameters:

is_univariate: bool: True iff all series in the panel have one variable
is_equally_spacedbool: True iff all series in the panel are equally spaced
is_equal_length: bool: True iff all series in the panel are of equal length
is_empty: bool: True iff panel has no variables or no instances
is_one_series: bool: True iff there is only one series in the panel of time series
has_nans: bool: True iff the table contains NaN values
n_instances: int: number of instances in the panel of time series
n_features: int: number of variables in the panel
feature_names: list of int or object: names of variables in the panel
dtypekind_dfip: list of DtypeKind enum: list of DtypeKind enum values for each feature in the panel, following the data frame interface protocol. In same order as feature_names.
feature_kind: list of str: list of feature-kind strings for each feature in the panel, coerced to "FLOAT" or "CATEGORICAL" type string. In same order as feature_names.
