NAME

====

Statistics::LinearRegression - simple linear regression

SYNOPSIS

========

Gather some data

    my @arguments = 1,2,3;

    my @values = 3,2,1;

Build model and predict value for some x using object

    use Statistics::LinearRegression;

    my $x = 15;

    my $y = my LR.new(@arguments, @values).at($x);

If you prefer bare functions, use :ALL

    use Statistics::LinearRegression :ALL;

    my ($slope, $intercept) = get-parameters(@arguments, @values);

    my $x = 15;

    my $y = value-at($x, $slope, $intercept);

DESCRIPTION

===========

LinearRegression finds slope and intercept parameters of linear function by minimizing mean square error.

Value at y is calculated using `y = slope × x + intercept`

TODO

====

  * R^2 and p-value calculation 

  * support for other objective functions

CHANGES

=======

  * 1.1.0 LR class exported by default, bare subroutines need :ALL
