解析 B 正确答案:B答案解析:“Statistical Concepts and Market Returns,” Richard A. DeFusco, Dennis W. McLeavey, Jerald E. Pinto, and David E. RunkleB is correct. For the positively skewed unimodal distribution, the mode is less than the median, which is less than the mean....

Normal distributions aresymmetric, unimodal, and asymptotic, and the mean, median, and mode are all equal. A normal distribution is perfectly symmetrical around its center. That is, the right side of the center is a mirror image of the left side. There is also only one mode, or peak, in...
为了避免上述unimodal所带来的问题，作者提出应当确保智能体能够在优先选择更好行为的情况下探索到各种各样可能的行为。一种可能的方式就是将策略分布定义为Q值的指数分布形式：\pi(\mathbf{a} \mid \mathbf{s}) \propto \exp Q(\mathbf{s}, \mathbf{a}) \\ 这种分布是玻尔兹曼分布（基于能量的模型）的一种...
A mixture of two normal distributions with equal standard deviations is bimodalonly if their means differ by at least twice the common standard deviation. ... If the means of the two normal distributions are equal, then the combined distribution is unimodal. ...

The standard normal curve, also known as Gauss curve, is a bell-shaped curve, that is unimodal, symmetric about the mean and have asymptotic tails. The area under the curve gives cumulative probabilities random variables takes in a continuous distribution....
Amixtureof two normal distributions will not be bimodal unless there is a large difference between their means — typically bigger than the sum of the individual distribution’sstandard deviations[6]. Unimodal Distributions. In comparison,unimodal distributionshave a single peak, or mode. ...
Bell-shaped: A bell-shaped picture, shown below,usually presents a normal distribution. Bimodal: A bimodal shape, shown below, has two peaks. ... If this shape occurs, the two sources should be separated and analyzed separately. Skewed right: Some histograms will show a skewed distribution to...
