The experimental analysis on the performance of a proposed method is a crucial and necessary task to carry out in a research. This paper is focused on the statistical analysis of the results in the field of genetics-based machine Learning. It presents a study involving a set of techniques which can be used for doing a rigorous comparison among algorithms, in terms of obtaining successful classi...

Risk phenomenon is one of the key characteristics of decision making in the fields of investment, issues associated with financial markets, and various economic activities. The present study was an attempt to evaluate the impact of different periods of life cycle of companies on the relevance of risk measures of companies. In this study, the collected data have been analyzed in three stages. Fi...

New rank tests for interactions in factorial designs are presented and applied to some common factorial designs with repeated measures. The resulting p-values of these tests are compared, along with those obtained by parametric and randomization tests.

Steganography refers to information or file that has been concealed inside a digital media. Steganalysis is used to detect and/or estimate potentially hidden information from observed data with a little or no knowledge about the steganography algorithm and its parameters. Current trend in steganalysis seems to suggest two extreme approaches (a) little or no statistical assumption about the imag...

Pain is subjective, while statistics related to pain research are objective. This review was written to help researchers involved in pain research make statistical decisions. The main issues are related with the level of scales that are often used in pain research, the choice of statistical methods between parametric or nonparametric statistics, and problems which arise from repeated measuremen...

background: use of single measurement of risk factors can distort their estimated effects, due to random error in measurements. the aim of this study was to examine the extent of underestimation in the estimated effect of common variables in physical exam i.e. systolic and diastolic blood pressure (sbp, dbp) and body mass index (bmi) on cardiovascular diseases in tehran lipid and glucose study ...

OBJECTIVE Recently, a parametric speaker system has been developed. However, the safety of the parametric speaker for the human body has not yet been demonstrated. Therefore, we studied the effects of parametric speaker sound on salivary hormones and carried out a subjective evaluation. METHODS Nine male subjects participated in this study. They completed three consecutive sessions: a 20-min ...

A non-parametric approach is proposed for shape design of free-form shells discretized into triangular mesh. The forms curvatures are used computing the fairness measures surface. defined as area offset surface and generalized form Gauss map. Gaussian curvature mean computed using angle defect cotangent formula, respectively, in field discrete differential geometry. Optimization problems formul...

A central theme in ecological research is to understand how species interactions contribute community dynamics. Species are the basis of parametric (model-driven) and nonparametric (model-free) approaches theoretical empirical work. However, despite their different interpretations across these approaches, measures have occasionally been used interchangeably, limiting our opportunity use differe...
