Determinants of Estimate Difference between Geometric Measure and Standard Deviation

چکیده

Measures of variation are statistical measures which assist in describing the distribution data set. These either used separately or together to give a wide variety ways measuring variability data. Researchers and mathematicians found out that these were not perfect, they violated algebraic laws possessed some weakness could ignore. As result facts, new measure known as geometric was formulated. The able overcome all weaknesses already existing measures. It obeyed laws, allowed further manipulation affected by outliers skewed sets. also determine more efficient than standard deviation its estimates always smaller those but did their main relationship how sample characteristics affect minimum difference between deviation. aim this study empirically ratio factor specifically certain variable such size, affects Data simulation concept achieve studies objectives. samples simulated individually under four different types distributions normal, Poisson, Chi-square Bernoulli distribution. A Hierarchical linear regression model fitted on skewed, binary countable sets results obtained. Based obtained, there is positive significant influenced existence size. increased while it decreased measure. For normal sets, increase size have any effect for

Measure the Fluctuation of the Stock Index According to Approximate Entropy and Standard Deviation

Abstract. The concept of entropy has been widely extended to other fields, including information theory and economic research. The economic financial sector of any country is the supplier of financial resources and real economic activities, which are divided into two parts: the money market and the capital market. In this paper, two criteria, approximate entropy and standard deviation have been...

Half standard deviation estimate of the minimally important difference in HRQOL scores?

In addition to statistical significance, it is important to evaluate the magnitude of differences in health-related quality of life over time. Interest in establishing the minimal difference that is clinically important or the minimally important difference has burgeoned over the last few years. This review summarizes some of the leading approaches to estimating the minimally important differen...

comparison of estimators of standard deviation, mean moving range and median moving range to estimate process standard deviation using autocorrelated data

independence of observations is a fundamental assumption in designing an x chart for individual observations. but unfortunately, the assumption of existence of independent data is not even approximately satisfied. in fact, there is one kind of autocorrelation in the data. this paper demonstrates, through simulating an ar(1) process, that the autocorrelation in the data has deep effect on x char...
