I made the following diagram in Tikz
. MWE is given below and it needs some refinement for nodes where they split into two arrows. Any help will be highly appreciated. Thanks
\documentclass{standalone}
\usepackage[latin1]{inputenc}
\usepackage{tikz}
\usetikzlibrary{calc,shapes,arrows}
\begin{document}
% Define block styles
\tikzstyle{block} =
[
rectangle
%, draw
% , fill=blue!20
, text width=5.0em
, text centered
, node distance=2.5cm
, rounded corners
, minimum height=1em
]
\tikzstyle{line} =
[
draw
, -latex'
]
\begin{tikzpicture}[node distance = 2cm, auto]
% Place nodes
\node [block] (Econo) {Econometrics};
\node [block, below left of=Econo, node distance=2cm, xshift=-1.0cm] (Theoretical) {Theoretical};
\node [block, below right of=Econo, node distance=2cm, xshift=1.0cm] (Applied) {Applied};
% Draw edges
\path[line] let \p1=(Econo.south), \p2=(Theoretical.north) in (Econo.south) -- +(0,0.5*\y2-0.5*\y1) -| (Theoretical.north);
\path[line] let \p1=(Econo.south), \p2=(Applied.north) in (Econo.south) -- +(0,0.5*\y2-0.5*\y1) -| (Applied.north);
% Place nodes
\node [block, below left of=Theoretical, node distance=2.5cm, xshift=0.75cm] (TheoreticalClassical) {Classical};
\node [block, below right of=Theoretical, node distance=2.5cm, xshift=-0.75cm] (TheoreticalBayesian) {Bayesian};
% Draw edges
\path[line] let \p1=(Theoretical.south), \p2=(TheoreticalClassical.north) in (Theoretical.south) -- +(0,0.5*\y2-0.5*\y1) -| (TheoreticalClassical.north);

Load
positioning
library and change allof =
to= of
in the node specifications. Your problems will be solved. Always use this library for positioning as this is more accurate. Also, it is better to usetikzset
instead of obsoletetikzstyle
as I did.
