Abstract : Three-dimensional graphs of mathematical statistical models are useful for the understanding of many phenomena. However, even with sophisticated expensive computer hardware and software, realistic rendering of 3-dimensional graphs is still a difficult task. For scientists with a limited budget, it is close to impossible. A simple inexpensive approach is to construct 3-D surfaces with LEGO bricks. Steps include: (a) simulate data (calculate outputs, i.e., z values from a design matrix of x, y inputs) for the surface via a favorite computing language or package; (b) roundoff data to the resolution of individual bricks, and tabulate data on sheets of paper, one sheet for each brick layer; (c) construct a wooden platform with axis tic marks and labels; and (d) construct the 3-D surface with bricks.
