STATISTICS PRESENT, NEAR FUTURE, AND BEYOND
Johnson, Richard A. The Korean Statistical Society 2001 Communications for statistical applications and me Vol.8 No.-
We berlin with a brief review of some important advances made in statistical theory over the last decade. The choice of topics is decidedly influenced by personal interests. Based on this review, we then propose some possible scenarios about the future of statistics.
Similarity Between Computer Control Systems and Community Planning
Light,Richard A,Johnson,R Curtis 한국화학공학회 1973 Korean Chemical Engineering Research(HWAHAK KONGHA Vol.11 No.5
The planning of a community's development and operations, whether for a small town or an international project, requires the allocation of resources to various areas of endeavor. This can best be done if a reasonably accurate estimate is made of the needs for corrective action and the effectiveness of it as a function of type and amount of expenditure. An estimate may be made of the amount of pollution and social conflict which may develop and of the effectiveness of various physical and human countermeasures (sewage disposal facilities, air pollution control, police, hospitals, etc.); on this basis a reasonable allccation may be made. Such a procedure forces one to establish value systems in order to ascertain social costs on comparable bases with each other. This is difficult. Few planners understand the philosophical implications of their actions. This approach, which bears great similarity to optimal process control by computer, will not solve the problems unless value systems can be established. Even when values cannot be adequately established, however, this approach to examining community problems allows decision makers to understand better the implications of their actions. This approach helps educators to better plan programs different from the traditionally narrow engineering curricula, and introduce the concept that technical tools and techniques have important applications at political and philosophical levels.

An Empirical Characteristic Function Approach to Selecting a Transformation to Normality
Yeo, In-Kwon,Johnson, Richard A.,Deng, XinWei The Korean Statistical Society 2014 Communications for statistical applications and me Vol.21 No.3
In this paper, we study the problem of transforming to normality. We propose to estimate the transformation parameter by minimizing a weighted squared distance between the empirical characteristic function of transformed data and the characteristic function of the normal distribution. Our approach also allows for other symmetric target characteristic functions. Asymptotics are established for a random sample selected from an unknown distribution. The proofs show that the weight function $t^{-2}$ needs to be modified to have thinner tails. We also propose the method to compute the influence function for M-equation taking the form of U-statistics. The influence function calculations and a small Monte Carlo simulation show that our estimates are less sensitive to a few outliers than the maximum likelihood estimates.

Maintenance of healthy endothelium is essential to vascular homeostasis, and preservation of endothelial cell function is critical for transplant allograft function. Damage of microvascular endothelial cells is now regarded as a characteristic feature of acute vascular rejection and chronic allograft nephropathy, which is an important predictor of graft loss and is often associated with transplant vasculopathy. In this review, we will discuss the role of microvascular endothelium, in renal allograft dysfunction, particularly as it relates to markers of endothelial dysfunction and endothelial repair mechanisms. We also discuss the potential for therapies targeting endothelial dysfunction and transplant graft vasculopathy.
