//Sample
First create your functions.

add_action("before_head_close","add_analytics_code");
function add_analytic_code()
{
echo "<script> var... </script>"; //The analytics code
}
?>

Then insert them with hook

<head>
<?php execute_action("after_head_open"); ?>
<title><?php echo $this->title; ?></title>
<?php execute_action("before_head_close"); ?>
</head>   
<body>```
