Description
The neutrino oscillation parameters are numerically extracted through the diagonalization of a general Majorana neutrino mass matrix whose elements are randomly generated within certain range of allowed values. The allowed values of each element are determined by using the latest neutrino oscillation experimental data within 3$\sigma$. The latest Planck upper bound on the sum of three absolute masses, $\sum \vert m_{i}\vert<0.12$ eV is imposed in the numerical analysis. Both normal and inverted hierarchical mass models satisfy the latest Planck cosmological bound, $\sum \vert m_{i}\vert<0.12$ eV, showing the possibility of both hierarchies within 3$\sigma$. Further, the detailed numerical analysis confirms that normal hierarchical mass model can give upto $\sum \vert m_{i}\vert\geq 0.06$ eV but the inverted hierarchical mass model can give upto $\sum \vert m_{i}\vert \geq 0.1$ eV. In both models, the value of $\theta_{23}$ lies below and above $45^{0}$. However, $\theta_{23}>45^{0}$ is more favourable for NH whereas $\theta_{23}<45^{0}$ is more favourable for IH.
