How does regression relate to linear algebra?
\n" ); document.write( "Linear regression relates to the linear model
\n" ); document.write( "which is the best least-squares fit to a set
\n" ); document.write( "of two-dimensional data points. The word
\n" ); document.write( "regression is used because this technique was
\n" ); document.write( "early on used to show that the children of
\n" ); document.write( "exceptional parents \"regress\" toward the average
\n" ); document.write( "rather than exhibit more exceptional quality.\r
\n" ); document.write( "\n" ); document.write( "What are some limitations of linear regression? What are the risks?
\n" ); document.write( "Some regression lines are much better fit to the data
\n" ); document.write( "than others. Therefore not all regression lines can
\n" ); document.write( "be used as a good predictor of values: in particular
\n" ); document.write( "the regression equation should not be used for prediction
\n" ); document.write( "of values which fall outside the range of the data used
\n" ); document.write( "to generate the regression equation.
