% This figure plots the binomial density for four different values % of N. % Figure caption: The pdf of the binomial mean X-bar when p = 0.4 % for four different values of n. As n increases, the % distribution becomes concentrated (the standard deviation of the % sample mean becomes small), with the center of the distribution % getting close to muX = 0.4 (the LLN). In addition, the % distribution becomes approximately normal (the CLT). % Set binomial parameters. p = 0.4; listOfNs = [4, 10, 25, 100]; for i = 1:4 n = listOfNs(i); xValues = 0:n; pdfValues = binopdf(xValues, n, p); subplot(2, 2, i) plot(xValues / n, pdfValues, 'ok', 'MarkerSize', 4) set(gca, 'Box', 'off', 'FontSize', 18, ... 'XTick', 0:0.2:1, 'YTick', [], 'TickDir', 'out') end % Close and set figure postion. set(gcf, 'Position', [200, 100, 1100, 900])
