创建相同的图形

Question

有人能帮我画出这个图吗？我试着画出来但结果却更糟了...

我的程序甚至也出现了问题……

我是 LaTeX 图形绘制的新手

\documentclass[a4paper]{book}
\usepackage{mathtools}
\usepackage{colonequals}
 \usepackage{mathrsfs}
  \usepackage{amssymb}
  \usepackage{amsthm}
  \usepackage{amsmath} 
   \usepackage{natbib}
   \usepackage{bm}
   \usepackage{mathdots}
   \usepackage{graphicx}
   \usepackage{caption}
   \usepackage{rotating, threeparttable, booktabs}

使用 TikZ：

\documentclass[a4paper]{book}
\usepackage[%
  labelfont=bf,labelsep=period,
  textfont=bf,
  width=\textwidth,
  justification=raggedright,
  singlelinecheck=false  
  ]{caption}

\usepackage{tikz}
\usetikzlibrary{positioning,backgrounds}
\usetikzlibrary{shapes.geometric, arrows.meta}
\tikzset{
    ovalnode/.style={
        ellipse, 
        very thick,
        fill=white,
        minimum height=1.5cm
        },
    rectnode/.style={
        rectangle,
        rounded corners=5mm,
        very thick,
        draw=blue,
        minimum height=1.5cm
        }
    }
\usepackage{caption}
\begin{document}
\begin{figure}

    \begin{tikzpicture}[framed]

        \node[below right=2cm and .5cm of A, ovalnode, draw=brown, minimum width=3cm] (A2) {Some text};
        \node[anchor=west, rectnode, minimum width=6cm, minimum height=2.5cm, above right=-1cm and 2cm of A] (NB) {};

        \node[rectnode, text width=4.5cm, minimum height=3cm, inner xsep=3mm, fill=white,below right=-1cm and -4cm of NB] (NF) {};
        \node[anchor=south, font=\bfseries, inner ysep=3mm] at (NF.south) {Some text X};

        % Legenda
