class PanelPdMultiIndex(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]

Data type: MultiIndex-ed pd.DataFrame specification of panel of time series.

Name: "pd-multiindex"

Short description:

a pandas.DataFrame, with row multi-index (instances, time), cols = variables

Long description:

The "pd-multiindex" mtype is a concrete specification that implements the Panel scitype, i.e., the abstract type of a collection of time series.

An object obj: pd.DataFrame follows the specification iff:

  • structure convention: obj.index must be a pair multi-index of type (Index, t), where t is one of Int64Index, RangeIndex, DatetimeIndex, PeriodIndex and monotonic. obj.index must have two levels (can be named or not).

  • instance index: the first element of pairs in obj.index (0-th level value) is interpreted as an instance index, we call it “instance index” below.

  • instances: rows with the same “instance index” index value correspond to the same instance; rows with different “instance index” values correspond to different instances.

  • time index: the second element of pairs in obj.index (1-st level value) is interpreted as a time index, we call it “time index” below.

  • time points: rows of obj with the same “time index” value correspond correspond to the same time point; rows of obj with different “time index” index correspond to the different time points.

  • variables: columns of obj correspond to different variables

  • variable names: column names obj.columns

Capabilities:

  • can represent panels of multivariate series

  • can represent unequally spaced series

  • can represent panels of unequally supported series

  • cannot represent panels of series with different sets of variables

  • can represent missing values

Parameters:
is_univariate: bool

True iff table has one variable

is_equally_spacedbool

True iff series index is equally spaced

is_equal_length: bool

True iff all series in panel are of equal length

is_empty: bool

True iff table 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 table

feature_names: list of int or object

names of variables in table

dtypekind_dfip: list of DtypeKind enum

list of DtypeKind enum values for each feature in the panel, following the data frame interface protocol

feature_kind: list of str

list of feature kind strings for each feature in the panel, coerced to FLOAT or CATEGORICAL type
