.. py:function:: within_trans(A, Tlens)

   Perform within-group transformation for unbalanced panel data.

   This function applies a within-group transformation to unbalanced panel data by
   removing individual-specific means from each submatrix.

   :param A: The full dataset, represented as a panel of stacked submatrices (one for each
             individual).
   :type A: 2D array-like, dtype=float64
   :param Tlens: The lengths of each submatrix (individual time series) in the panel.
   :type Tlens: 1D array-like, dtype=int

   :returns: **B** -- The dataset after applying the within-group transformation, with
             individual-specific means removed.
   :rtype: 2D array-like, dtype=float64
