加拿大essay代写:随机效应模型的研究报告分析

为了进行分析,从75份不同的报告中观察了结果。所代表的一些报告有一个完全独立的研究小组。在不同的报告中,约有68份报告对工作后的结果进行了评估,8份报告也收集了一些后续信息。这些后效数据是根据一些终点得出的。另外8位也收集了一些后续信息。其中只有7项包括后续数据。最后的研究样本包括来自第21届CLCC的例子,以及其他一些由不同组织支持的本地项目。每一种效应都因任何特定的样本偏差而得到纠正。

为了研究该模型,对随机效应模型进行了分析。为了实现一致的策略,就要对每个分析做效果大小的计算。在第一个分析中,从不同的程序,有在那里的post,已研究的平均效果大小,以获得一个效果。采用随机效应模型进行分析。这个随机效应模型做了一个假设,即SMD中可能存在变异,这在所有的研究中都存在。在整个分析过程中,使用了大约0.5%的概率。在0.5个置信区间的帮助下,报告了对分组进行研究的平均影响。此外,还进行了同质性分析,以便在SMD估计相同的总体效应时进行分析。该分析基于Q统计量,Q统计量以k-1自由度左右的卡方分布。这里的valye (k)是研究的数量。除此之外,还得到了I2统计量。在分析之后,两个主要的方法学特征被编码为存在或不存在。此外,还使用了随机数据。

In order to do the analysis, the results had been observed from 75 different reports. Some of the reports which had been represented had a completely individual research group. Among the different reports, around 68 did the assessment of the outcomes at post, 8 also collected some of the follow up information. These post effects data had been based on some of the end points. Also the 8 also collected some of the follow up information. Only 7 of these included the follow up data. The final study sample consisted of the examples from 21st CLCC and some other kind of local initiatives which had been supported by different organizations. Each of the effect had been corrected for any specific sample bias.

In order to study the model, a random effects model had been analyzed. In order to implement the consistent strategy was to do the calculation of the effect size for each analysis. In the first analysis from the different programs which were there at post, the average of the effect sizes has been studied to get one effect. A random effect model had been used for the purpose of the analysis. This random effect model does the assumption that there may be variation in the SMD’s which are there across the studies. Throughout the analysis, around 0.5 % probability was used. The mean impact for doing the study of the groupings had been reported with the help of 0.5 confidence intervals. Other than this, the homogeneity analysis had also been conducted in order to do the analysis if the SMD’s estimated the same population effect. This analysis had been based on the Q statistic which had been distributed as a chi-square which has around k-1 degrees of freedom. Here the valye of k is the number of studies. Other than this the I2 statistic has also been obtained. After the analysis, two primary methodological features had been coded as present or absent. In addition to this the use of the randomized data had been given.
