Data.std(column=None, sigma=None, bounds=None)

Find standard deviation value of col_a data column.

Parameters:

column (index) – Column to look for the maximum in

Keyword Arguments:

• sigma (column index or array) – The uncertainty noted for each value in the mean

• bounds (callable) – col_a callable function that takes col_a single argument list of numbers representing one row, and returns True for all rows to search in.
