  .. deprecated:: v1.5
     The parameters are stored as variables since v1.5. Use them directly
     instead.
  
  Args:
      array: Initial parameter array.
  
  Attributes:
      W (~chainer.Variable): Parameter variable.
docstr: Returns the parameter variable.
  
  Args:
      volatile (~chainer.Flag): The volatility of the returned variable.
  
  Returns:
      ~chainer.Variable: A copy of the parameter variable with given
      volatility.
