(τ2) was estimated by calculation ofT2using the DerSimonian and Laird method, and to estimate the ratio of true heterogeneity to total variance in observed effects, the I2statistic was calculated [35]. In subgroup analyses, separate estimates ofτ2were made for each individual subgroup. The...
It can be hard to find the perfect sample size for statistically sound results. Here we reveal methods and tools for effective sample size determination.
We examine various methods to estimate the effective sample size for construction of confidence intervals for survival probabilities. We compare the effect... FJ Dorey,EL Korn - 《Statistics in Medicine》 被引量: 64发表: 2010年 On sample sizes to estimate the protective efficacy of a vaccine ...
Some clinical trials perform repeated measurement over time and estimate clinically relevant change in an instrument's score with global ratings of perceived change or so-called transition questions. The conceptual and methodological difficulties in estimating the magnitude of clinically relevant change over...
period, like a year. In the case of our fictional calorie counting device, this is likely to be a one-off purchase, but if it’s a consumable you’re selling, purchase frequency will be far higher. Use your industry data andconsumer brand researchto estimate this figure – and be ...
