代写论文:SMD研究

为了研究该模型,对随机效应模型进行了分析。为了实现一致性策略,需要对每个分析的效果大小进行计算。在第一次的分析中,在不同的项目中,平均的效果大小被研究得到一个效果。采用随机效应模型进行分析。这种随机效应模型的假设是,在研究中,SMD中可能存在变异。在整个分析过程中,大约使用了0.5%的概率。在0.5个置信区间的帮助下,报告了分组研究的平均影响。除此之外,还进行了同质性分析,以便在SMD估计相同的人口效应时进行分析。这一分析是基于Q统计量,它被作为一个k-1自由度的卡方分布。这里k的值是研究的数量。除此之外,还得到了I2统计量。在分析之后,有两种主要的方法特征被编码为现在或不存在。除此之外,还使用了随机数据。

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.
