Multiple comparisons for survival data with propensity score adjustment

Zhu, Hong; Lu, Bo - In: Computational Statistics & Data Analysis 86 (2015) C, pp. 42-51

multiple comparisons are suggested. Multiple Comparisons with a Control (MCC) compare every other group to a control group with … procedures for multiple comparisons and provides simultaneous confidence intervals. The proposed methods are applied to two real … respect to survival outcomes, for determining which groups are associated with lower risk than the control. Multiple …

Adaptive FWER control procedure for grouped hypotheses

Zhao, Haibing - In: Statistics & Probability Letters 95 (2014) C, pp. 63-70

In this paper, we discuss the multiple testing problem for grouped hypotheses. We propose weighted p-value procedures, which are theoretically shown to control the family-wise error rate and be more powerful than existing methods. Simulation studies further confirm the theoretical analysis...

Monotonicity of certain integrals involving gamma distributions and their applications in multiple comparisons

Misra, Neeraj; Arshad, Mohd. - In: Statistics & Probability Letters 85 (2014) C, pp. 144-152

Barlow and Gupta (1969) and Alam (1970) studied the monotonicity of two integrals, involving gamma distributions, that arise in certain ranking and selection problems. In this paper, we shall unify their results by studying the monotonicity of two generalized versions of integrals considered by...

Comparing exponential location parameters with several controls under heteroscedasticity

Malekzadeh, A.; Kharrati-Kopaei, M.; Sadooghi-Alvandi, S. - In: Computational Statistics 29 (2014) 5, pp. 1083-1094

control groups when the scale parameters may be unequal. Using the parametric bootstrap approach, we develop a new multiple … comparisons procedure when the scale parameters and sample sizes are possibly unequal. We then present a simulation study in which …

The computation of bivariate normal and t probabilities, with application to comparisons of three normal means

Kim, Jongphil - In: Computational Statistics & Data Analysis 58 (2013) C, pp. 177-186

A novel method for the computation of the bivariate normal and t probability is presented. With suitable transformations, the probability over sets can be easily computed using exact one-dimensional numerical integration. An important application includes computing the exact critical points for...

Simultaneous confidence intervals for comparing margins of multivariate binary data

Klingenberg, Bernhard; Satopää, Ville - In: Computational Statistics & Data Analysis 64 (2013) C, pp. 87-98

In many applications two groups are compared simultaneously on several correlated binary variables for a more comprehensive assessment of group differences. Although the response is multivariate, the main interest is in comparing the marginal probabilities between the groups. Estimating the size...
