What's the best way to initialize an array in PowerShell?

For example, the code

$array = @()
for($i=0; $i -lt 5;$i++)
{
    $array[$i] = $FALSE
}

generates the error

Array assignment failed because index '0' was out of range.
At H:\Software\PowerShell\TestArray.ps1:4 char:10
+         $array[$ <<<< i] = $FALSE
