.. py:function:: delete_period_obs(A, Tlens, h, fromStart=True)

   Delete `h` observations from the start or end of each submatrix.

   This function removes the first `h` observations from each submatrix in unbalanced
   panel data to create a lag effect. If `fromStart` is set to `False`, the function
   will delete the last `h` observations instead.

   :param A: The full dataset, represented as a stacked 1D array.
   :type A: 1D array-like, dtype=float64
   :param Tlens: The lengths of each submatrix (individual time series) in the panel.
   :type Tlens: 1D array-like, dtype=int
   :param h: The number of observations to delete from each submatrix.
   :type h: int
   :param fromStart: If `True`, delete the first `h` observations; if `False`, delete the last `h`
                     observations.
   :type fromStart: bool, default=True

   :returns: **B** -- The dataset after deleting `h` observations from each submatrix.
   :rtype: 2D array-like, dtype=float64
