\usage{
ll(O1, O2, O, N, E, window_size)
}
\arguments{
\item{O1}{observed absolute frequency of node}

\item{O2}{observed absolute frequency of collocate}

\item{O}{observed absolute frequency of collocation}

\item{N}{corpus size}

\item{E}{expected absolute frequency of collocation (already adjusted to window size)}

\item{window_size}{total window size around node (left neighbour count + right neighbour count)}
}
