答案解析: A distribution with positive excess kurtosis has a higher percentage of small deviations from the mean than normal. So it is more “peaked” than a normal distribution. A distribution with positive skew has a mean > mode.统计:共计75人答过,平均正确率57.33%问题:进入高顿部落发帖帮助...
Skewness is the measurement of a a coefficient that has the ability to be positive, negative or neutral (zero). The coefficient of the skew is the measurement of the magnitude of the symmetry in the distribution of outcomes of a specific data set of occurrences. The skewness enables traders ...

65% below the age of 35. If you plot the distribution of the age of the population of India, you will find that there is a hump on the left side of the distribution, and the right side is comparatively planar. In other words, we can say that there’s a skew toward the end, ...

Differences between patients with culture-negative or culture-positive PJI were assessed for significance using the independent-samples t test for continuous data showing a normal distribution, the Mann‒Whitney U test for continuous data showing skew, or the chi-squared test or Fisher exact test ...
The matrix S is skew-symmetric, and thus 〈Sx,x〉Cn=〈Sa,a〉+〈Sb,b〉+i(〈Sa,b〉−〈Sb,a〉)=i〈Sa−STa,b〉=2i〈Sa,b〉. The matrices G and H are symmetric, and thus 〈Hx,x〉Cn=〈Ha,a〉+〈Hb,b〉+i〈Ha−HTa,b〉=〈Ha,a〉+〈Hb,b〉 and 〈Gx,x〉Cn=〈Ga,a...
In the statistical distribution of heavy metals, As, Cr and Cu are slightly right-skewed, with skewness indexes less than 1 and peak indexes (kurtosis) that is not high. However, the content distributions of Cd and Hg are seriously right-skewed, with skew indexes of 3.99 and 4.61, and co...
