For a positively skewed unimodal distribution, which of the following measures is most accuratelydescribed as the largest?[单选题] A. Median B. Mean C. Mode 相关知识点: 试题来源: 解析 B 正确答案:B答案解析:For a positively skewed unimodal distribution, the mode is less than the median, ...
Several theorems are obtained concerning the unimodality of spherically symmetric distribution functions. These theorems are used to show that a class of spherically symmetric infinitely divisible distribution functions that contains the class of spherically symmetric stable distribution functions is unimodal....
Thus, \(\bar{t}\) has a projected normal distribution, which is unimodal and rotationally symmetric with respect to its mean direction \(\mu _{\bar{t}}/||\mu _{\bar{t}}||_{I_{r}}\). The scalar \(||\mu _{\bar{t}}||_{I_{r}}=\lambda _{t}\) is a measure of the...
Topp-Leone odd log-logistic exponential distribution: Its improved estimators and applications. Further, the hazard rate function of the new model can be monotone, unimodal, constant, J-shaped, constant-increasing-decreasing and decreasing-increasing-decreasing and bathtub-shaped. Our main focus is on...
Like other spike-in controls, the synthetic DNA ladder reflects the technical variation that accumulates during experimental steps of library preparation and sequencing. This is apparent in the symmetric, unimodal distribution of k-mer counts at each level of cn, which is broader in the experimental...
Local wave activity (LWA) measures meandering of the jet stream, large values often linked to disruptions of the jet and extreme weather Observed probability distribution of LWA is positively skewed due to nonlinearity in the zonal advection (LWA-zonal wind interaction) Frequency of large LWA events...

In particular, we have an explicit critical value βc(1) for the bias such that the speed is positive for β∈(1,βc(1)) and is zero for β≥βc(1). From this formula, we see that the speed is a unimodal function of the bias, see Fig. 3. The formula also allows to study ...
We observe that the distribution of maximal clique degrees is unimodal in the minimally wired null model and qualitatively bimodal in the empirical data (see Fig. 2a), though we report statistically that we cannot reject that it is unimodal (p = 0.210, dip test (Hartigan and Hartigan 1985...
Estimates of the location and scale parameters, linear in the order statistics of a Type II censored or complete sample, from a continuous symmetric unimodal distribution satisfying certain conditions are obtained. Their coefficients are... KC Lai - 《Naval Research Logistics Quarterly》 被引量: 5...
