Casella 在福特汉姆大学完成了他的本科教育,在普渡大学完成了研究生教育。他曾在罗格斯大学、康奈尔大学和佛罗里达大学任教。他的贡献集中在统计学领域,包括蒙特卡洛方法、模型选择和基因组分析。他在贝叶斯和经验贝叶斯方法方面特别活跃,其作品与斯坦因现象相联系,涉及评估和加速马尔科夫链蒙特卡洛方法的收敛性,如他的Rao-Blackwellisation技术,以及将拉索重塑为具有独立拉普拉斯先验的贝叶斯后验模式估计。
Casella于1988年被任命为美国统计学会和数学统计研究所的研究员,并于1989年成为国际统计学会的当选研究员。2009年,他被任命为西班牙皇家科学院外籍院士。
Roger Lee Berger 是美国统计学家和教授,与合作者 George Casella 于1990年首次出版《Statistical Inference》一书。
"If E|g(X)|=∞, we say that Eg(X) does not exist. (Ross 1988 refers to this as the "law of the unconscious statistician." We do not find this amusing.)"
"The point here is that normality comes from sums of "small" (finite variance), independent disturbances."
"Definition 1.2.4 Given a sample sapce S and an association sigma algebra B, a probability function is a function P with domain B that satisifies 1. P(A) >= 0 for all A in B. 2. P(S) = 1. 3. If A1, A2, ... in B are parwise disjoint, then P(Union(Ai)) = sum(P(Ai)) The three properties given in Definit"
"The probability definition deals with one probability structure, but the statistis definition deals with an entire family."
"The property of consistency is concerned with the asymptotic accuracy of an estimator: Does it converge to the parameter that it is estimating? In this section we look at a related property, efficiency, which is concerned with the asymptotic variance of an estimator."
""I've wasted time enough," said Lestrade rising. "I believe in hard work and not in sitting by the fire spinning fine theories.""
"ANOVA belies its name in that it is not concerned with analyzing variances but rather with analyzing variation in means."
"The ANOVA null is the intersection of more easily understood univariate hypotheses. Most interesting inferences in an ANOVA can be expressed as contrasts or sets of contrasts."
