英国论文代写-预期收益
预期收益可以以这种方式增加。另一方面，根据文章，随机行走理论描述了与安全相关的价格水平未来路径在本质上是没有什么可预测性的。这是与累积随机数系列路径相比较。在统计方面，理论认为价格的连续变化具有独立性。这种独立性在具有随机相同分布的变量中出现。这意味着最简单的就是价格序列和变化没有任何内存。这进一步意味着，过去发生的事不能以任何有意义的方式来预测未来。
这就是为什么在文章中对股票价格的随机漫步理论给予支持的原因。股票价格中的随机游走理论包含两个不同的假设。首先是价格的连续变化具有独立性，其次，价格的变化与一定的概率分布一致。这个假设已经在本文中独立地讨论过了。在阅读这篇论文的时候，有一种清晰的事实，即论文为随机漫步假说提供了巨大而有力的支持。然而，在经济学家的商业和研究中，人们不可能声称毫无疑问地建立了一个假设。总是有更多的测试，可以倾向于假设有效性确认或之前得到的结果反对。在最后的论文段落中，文章对未来的研究提出了一些建议。
Expected gains can be increased in this manner. On the other hand, as per the article, the random-walks theory depicts that the price level future pathway related to security is nothing much predictable in nature. This has been compared to the cumulated random numbers series path. In terms of statistics, the theory states that successive changes in price have independence (Fama, 1965). This independence comes forward in the variables with random identical distribution. This implies most simply that the price series and the changes do not have any memory.
This further means that what has occurred in the past cannot be utilized for prediction of the future in any meaningful manner. This is the reason why favour in the article is given to the random walks theory of stock prices. The random walks theory within the prices of stock involves 2 distinct hypotheses. First is successive changes in prices has independence and secondly, the changes in price have conformance to certain distribution of probability. The hypothesis has been discussed in this article independently. When reading the paper, there is clarity on the fact that the paper has offered enormous and strong support for random walk hypothesis. However, within business and research by economists, it is not possible for one to claim that a hypothesis has been established without any doubt (Fama, 1965). Always there are more tests that can be done either tending towards hypothesis validity confirmation or previously obtained results opposition. Within the final paper paragraphs, the paper indulged in suggesting certain directions for future research.
