%corrdemo ----------------------------------------------------------------------- Demo on Correlation Coefficient Description Shows scatterplot and correlation for a given data file. Syntax %corrdemo(corr= , size=, outfile=' ', data= , dev= , title= ,axis1=, axis2=, symbol=, plot=); corr - draw a sample from a population with a correlation of this size. size - the sample size, how many pairs to draw outfile - saves the graph as a .gif file with the given name dev - specifies the device used for saving the graph, which determines the size of the graph title - the title displayed at the top of the graph axis1 - options for the "axis1" statement (the x axis) axis2 - options for the "axis2" statement (the y axis) symbol - options for the "symbol" statement plot - options for the "plot" statement Examples %corrdemo %corrdemo(size=500, corr=0.9) %corrdemo(size=500, corr=0.9, outfile="c:\temp\corr9.gif") %corrdemo(size=500, corr=0.7, outfile="c:\temp\corr7.gif", symbol = i=r) %corrdemo(size=200, corr=-0.70, outfile="c:\temp\whatcorr.gif", title="What is the Correlation Coefficient?")
