The pseudorapidity dependence of the double NBD parameters: $\langle n \rangle_1$, $\langle n \rangle_2$, $k_1$, and $k_2$ in p$-$Pb collisions at $\sqrt{s_{\rm NN}}=5.02$ TeV in comparison with pp measurements at $\sqrt{s} = 0.9$, 7, and 8 TeV. For p$-$Pb collisions, the $\langle n \rangle_1$ and $\langle n \rangle_2$ values are scaled by the $\langle \Npart \rangle$/2.
