A robustness study to investigate the performance of six procedures for comparing two or more groups, under several circumstances, has been carried out. The study was divided in four parts. The first three were Monte-Carlo studies, and the fourth was a study on empirical data. The six procedures were the ANOVA (or its special case, the Student's t) procedure (1), the Satterthwaite (or its speci...

Methods for combining 2×2 contingency tables from multiple studies are reviewed and new methods are proposed. Methods for combining 2×2 contingency tables from multiple studies are presented in the context of three different statistical models: the constant coefficient model, the varying coefficient model, and the random coefficient model. The constant coefficient confidence intervals have unac...

Conditional adjustment of cooperativeness to the expected pay-off might be a useful strategy to avoid being exploited in public good situations. Parental care provided towards all offspring in a communal nest (containing offspring of several females) resembles a public good. Females indiscriminately caring for all young share the costs equally, but the pay-off may vary depending on their contri...

Many standard methods for modeling interaction in two way ANOVA require mn interaction parameters, where m and n are the number of rows and columns in the table. By viewing the interaction parameters as a matrix and performing a singular value decomposition, one arrives at the Additive Main EEects and Multiplicative Interaction (AMMI) model which is commonly used in agriculture. By using only t...

Support vector regression (SVR) has been widely used to reduce the high computational cost of computer simulation. SVR assumes input parameters have equal sample sizes, but unequal sizes are often encountered in engineering practices. To solve this issue, a new prediction approach based on SVR, namely as high-low level (HL-SVR) is proposed for data modeling paper. The consists low-level models ...

Abstmct Handover in heterogeneous cellular networks is one of the hottest topics for the wireless networks beyond the third generation. This paper presents a new downlink soft handover algorithm to solve the serious “power exhausting” problem during the traditional handover process in heterogeneous cellular systems. The power exhausting problem occurs when in the traditional handover process, t...

Proper arrangement of facility layout is a key issue in management that influences efficiency and the profitability of the manufacturing systems. Parallel Row Ordering Problem (PROP) is a special case of facility layout problem and consists of looking for the best location of n facilities while similar facilities (facilities which has some characteristics in common) should be arranged in a row ...
