PanelDfList

class PanelDfList(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: list-of-pandas.DataFrame based specification of panel of time series.

Name: "df-list"

Short description:

a list of pandas.DataFrame, with list index = instances, data frame rows = time points, data frame cols = variables

Long description:

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

An object obj: list follows the specification iff:

structure convention: obj must be a list of pandas.DataFrames. Individual list elements of obj must follow the "pd.DataFrame" mtype convention for the "Series" scitype.
instances: instances correspond to different list elements of obj.
instance index: the instance index of an instance is the list index at which it is located in obj. That is, the data at obj[i] correspond to observations of the instance with index i.
time points: rows of obj[i] correspond to different, distinct time points, at which instance i is observed.
time index: obj[i].index is interpreted as the time index for instance i.
variables: columns of obj[i] correspond to different variables available for instance i.
variable names: column names obj[i].columns are the names of variables available for instance i.

Capabilities:

can represent panels of multivariate series
can represent unequally spaced series
can represent panels of unequally supported series
can 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
