线性模型选择中广义交叉验证准则的一个注记
Cross-validation criteria in linear model selection are approached from a coordinate free point of view. A new generalised cross-validation criterion is derived and shown to contain the ordinary and the existing generalised cross-validation criteria as special cases.

二次型的渐近分布及其拟合检验应用
Let $Z_1, Z_2,\cdots$, be independent and identically distributed random variables and $\{c_{ijn}\}$ real numbers; put $T_n = \sum^n_{i,j = 1} c_{ijn}Z_iZ_j$. This paper gives conditions under which the distribution of $T_n - ET_n$ converges to the distribution of $\sum \Upsilon_m(Y_m^2 - 1)$ with $\{\Upsilon_m\}$ a real sequence and $Y_1, Y_2,\cdots$ independent $N(0, 1)$ random variables. The results are applied to the calculation of the asymptotic distributions of test…
