Title

multicoint_graph -- Diagnostic graphs after multicoint

Package

This command is part of the multicoint library
(main, multicoint_sim,
multicoint_cv).

Syntax

multicoint_graph [, options]

onepanel only the residual u_t panel

twopanel flows + cumulated series

fourpanel default (flows, cumulated, S_t, u_t)

sixpanel adds Y vs X scatter and u_t histogram

scheme(name) override scheme (default s2color)

name(name) name for combined graph (default mc_diag)

title(string) override title

note(string) override note

save(filename) export combined graph to file

Description

multicoint_graph produces a tiled diagnostic plot summarising the
output of the most recent multicoint estimation. Panels (in order):

1. Flow series y_t and x_t over time.

2. Cumulated I(2) series Y_t and X_t.

3. Cumulated equilibrium error S_t = Σ Z_s (Granger-Lee stage 1).

4. Multicoint regression residual u_t.

5. Long-run scatter Y vs X with linear fit (six-panel only).

6. Histogram of u_t with N(0,σ²) overlay (six-panel only).

Examples

1. Default four-panel layout

multicoint y x, est(taols) test(all)

multicoint_graph

2. Six-panel with PDF export

multicoint_graph, sixpanel save(mcdiag.pdf)

3. Only the residual trace
