The help page of the Box.test function (stats) states that the Ljung-Box test
was published in:

Ljung, G. M. and Box, G. E. P. (1978), On a measure of lack of fit in time
series models. Biometrika 65, 553--564. 

The page numbers are incorrect. The correct citation should be as follows:

Ljung, G. M. and Box, G. E. P. (1978), On a measure of lack of fit in time
series models. Biometrika 65, 297--303. 

Yours,

Peter
