There are lots of very good reasons not to program in TCSH. If you're not being forced to use it, I'd suggest learning the Bourne shell.

But meanwhile, this syntax works both in BASH and TCSH:
Code:
./command <<EOF
stuff to feed into command's stdin
This can include $VARIABLES and `commands`
EOF

The final EOF must be at the beginning of the line with NO spaces in front.

Statistics::Basic::LeastSquareFit(3pm)			User Contributed Perl Documentation		    Statistics::Basic::LeastSquareFit(3pm)

NAME
Statistics::Basic::LeastSquareFit - find the least square fit for two lists SYNOPSIS
A machine to calculate the Least Square Fit of given vectors x and y. The module returns the alpha and beta filling this formula: $y = $beta * $x + $alpha for a given set of x and y co-ordinate pairs. Say you have the set of Cartesian coordinates: my @points = ( [1,1], [2,2], [3,3], [4,4] ); The simplest way to find the LSF is as follows: my $lsf = lsf()->set_size(int @points); $lsf->insert(@$_) for @points; Or this way: my $xv = vector( map {$_->[0]} @points ); my $yv = vector( map {$_->[1]} @points ); my $lsf = lsf($xv, $yv); And then either query the values or print them like so: print "The LSF for $xv and $yv: $lsf "; my ($yint, $slope) = my ($alpha, $beta) = $lsf->query; LSF is meant for finding a line of best fit. $beta is the slope of the line and $alpha is the y-offset. Suppose you want to draw the line. Use these to calculate the "x" for a given "y" or vice versa: my $y = $lsf->y_given_x( 7 ); my $x = $lsf->x_given_y( 7 ); (Note that "x_given_y()" can sometimes produce a divide-by-zero error since it has to divide by the $beta.) Create a 20 point "moving" LSF like so: use Statistics::Basic qw(:all nofill); my $sth = $dbh->prepare("select x,y from points where something"); my $len = 20; my $lsf = lsf()->set_size($len); $sth->execute or die $dbh->errstr; $sth->bind_columns( my ($x, $y) ) or die $dbh->errstr; my $count = $len; while( $sth->fetch ) { $lsf->insert( $x, $y ); if( defined( my ($yint, $slope) = $lsf->query ) { print "LSF: y= $slope*x + $yint "; } # This would also work: # print "$lsf " if $lsf->query_filled; } METHODS
This list of methods skips the methods inherited from Statistics::Basic::_TwoVectorBase (things like insert(), and ginsert()). new() Create a new Statistics::Basic::LeastSquareFit object. This function takes two arguments -- which can either be arrayrefs or Statistics::Basic::Vector objects. This function is called when the leastsquarefirt() shortcut-function is called. query() LSF is meant for finding a line of best fit. $beta is the slope of the line and $alpha is the y-offset. my ($alpha, $beta) = $lsf->query; y_given_x() Automatically calculate the y-value on the line for a given x-value. my $y = $lsf->y_given_x( 7 ); x_given_y() Automatically calculate the x-value on the line for a given y-value. my $x = $lsf->x_given_y( 7 ); "x_given_y()" can sometimes produce a divide-by-zero error since it has to divide by the $beta. This might be helpful: if( defined( my $x = eval { $lsf->x_given_y(7) } ) ) { warn "there is no x value for 7"; } else { print "x (given y=7): $x "; } query_vector1() Return the Statistics::Basic::Vector for the first vector used in the computation of alpha and beta. query_vector2() Return the Statistics::Basic::Vector object for the second vector used in the computation of alpha and beta. query_mean1() Returns the Statistics::Basic::Mean object for the first vector used in the computation of alpha and beta. query_variance1() Returns the Statistics::Basic::Variance object for the first vector used in the computation of alpha and beta. query_covariance() Returns the Statistics::Basic::Covariance object used in the computation of alpha and beta. OVERLOADS
This object is overloaded. It tries to return an appropriate string for the calculation, but raises an error in numeric context. In boolean context, this object is always true (even when empty). AUTHOR
