  This deals with the Stancu variant of (p, q)-Sz\'asz-Mirakyan-Baskakov
operators. Estimation of moments and establishing few basic approximation
results which comprise weighted approximation and direct estimates in view of
modulus of continuity is the aim of this paper. Steklov mean method has been
used for linear approximation. For the particular case {\alpha} = 0, \b{eta} =
0, we get (p, q) -Sz\'asz-Mirakyan-Baskakov operators.
