Webkurtosis: [noun] the peakedness or flatness of the graph of a frequency distribution especially with respect to the concentration of values near the mean as compared with the normal distribution. WebObviously, the kurtosis of the distribution during displacement process is greater than zero, so the peakedness is steep. However, the kurtosis under static condition is less than zero, so the peakedness is gentle. There are positive and negative skewness values, so the asymmetry of the distribution curves of the two conditions is similar.

WebThis paper gives a modiﬁed ERM which works when the service distribution is a two-term hyper-exponential distribution. We develop the method by extending a peakedness calculation given by Machi-hara [11]. While Machihara’s approximation works only for certain offered loads, the modiﬁed approx-imation works for all loads.

WebJul 29, 2024 · Kurtosis is usually thought of as denoting heavy tails; however, many decades ago, statistics students were taught that higher kurtosis implied more "peakedness" versus the normal distribution.
