pandas: powerful Python data analysis toolkit, Release 0.18.1
If the axis is a MultiIndex (hierarchical), count along a particular level, collapsing
intoa DataFrame
ddof : int,default 1
degrees of freedom
numeric_only : boolean, default None
Include only float, int, boolean data. If None, will attempt to use everything, then
use only numeric data
Returns std : DataFrame orPanel (if level specified)
pandas.Panel.var
Panel.var(axis=None, skipna=None, level=None, ddof=1,numeric_only=None,**kwargs)
Return unbiased variance over requested axis.
Normalized by N-1 by default. This can be changed using the ddof argument
Parameters axis : {items (0),major_axis (1), minor_axis (2)}
skipna : boolean, default True
Exclude NA/null values. If an entire row/column is NA, the result will be NA
level : int or level name, default None

degrees of freedom
numeric_only : boolean, default None
Include only float, int, boolean data. If None, will attempt to use everything, then

Panel.add_prefix(prefix)
Concatenate prefixstring with panel items names.
Panel.add_suffix(suffix)
Concatenate suffix string with panel items names.
Panel.drop(labels[,axis,level,inplace,...])
Return new object with labels inrequested axis removed.
Panel.equals(other)
Determines if two NDFrame objects contain the same elements.
Panel.filter([items,like,regex,axis])
Restrict the info axis toset of items orwildcard
Panel.first(offset)
Convenience method for subsetting initial periods oftime series data based on a date offset.
Panel.last(offset)
Convenience method for subsetting final periods of time series data based on a date offset.

Panel.rename([items,major_axis,minor_axis])
Alter axes input function or functions.
Panel.sample([n,frac,replace,weights,...])
Returns a random sample ofitems from an axis of object.
Panel.select(crit[,axis])
Return data corresponding to axis labels matching criteria
Panel.take(indices[,axis,convert,is_copy])
Analogous to ndarray.take
