In this article we examine the impact of daily trade turnover on the day-of-the-week effect in emerging stock markets. The empirical analysis was made by using Vilnius Stock OMX equities return data. The main method suggested for analysis was based on formation of three portfolios with equities having low, medium and high daily turnover. By applying traditional statistical research methods, suc...

Confluent with the single dimension of time, breach of time-reversal symmetry is usually perceived as a one-dimensional concept. In its ultimate realization–the one-way guiding device–it allows optical propagation in one direction, say +z, and forbids it in the opposite direction, −z. Hence, in studies of time-reversal asymmetry the mapping t 7→ −t is naturally associated with z 7→ −z. However,...

In this manuscript we present various robust statistical methods and show how to apply them in R using the WRS2 package. We elaborate on robust location measures and present robust t-test versions for independent and dependent samples. We focus on robust one-way and higher order ANOVA strategies including mixed designs (“betweenwithin subjects”). Finally, we elaborate on running interval smooth...

The study aimed to compare health status and lifestyle in university students. The participants were college freshmen from physical education majors (N = 195, Mean = 20.9, SD = 1.87) and the school of Urban and Environmental majors (N = 195, Mean = 21.73, SD = 0.93) in Dalian, China. The Diagnostic Inventory of Health and Life habit (DIHAL.2) scale (Tokunaga, 2003) was administered to all parti...

‎a $mu$-way $(v,k,t)$ $trade$ of volume $m$ consists of $mu$‎ ‎disjoint collections $t_1$‎, ‎$t_2‎, ‎dots t_{mu}$‎, ‎each of $m$‎ ‎blocks‎, ‎such that for every $t$-subset of $v$-set $v$ the number of‎ ‎blocks containing this t-subset is the same in each $t_i (1leq‎ ‎i leq mu)$‎. ‎in other words any pair of collections ${t_i,t_j}$‎, ‎$1leq i< j leq mu‎$ is a $(v,k,t)$ trade of volume $m$. in th...
