    Such Bessel functions have been used recently at the statistical laboratory of the University of California in preparation of certain statistical tables to appear in Annals of Math. Statistics. See also: J. Wishart, “A note on the distribution of the correlation ratio,” Biometrika, v. 24, 1932, p. 454, formula (27). The most extensive tables of ${I_n}(x)$ are in B.A.A.S., Math. Tables, v. 6, Bessel Functions, part I, Cambridge, 1937, Tables VI and VIII. J. W. Nicholson, Phil. Mag. s. 6, v. 20, 1910, p. 938-943. The $Q$’s may be checked by the relation ${Q_m}(1) = {4^m}$; also $m(m + 1)\int _0^1 {{t^{3m - 1}}{Q_m}({t^{ - 2}})dt} = {2^{2m + 1}}|{B_{m + 1}}|$, where ${B_k}$ is the $k$th Bernoulli number, in the notation of Lucas.
