As sample size was small and regression residuals not normally distributed we used bootstrap resampling (2000 iterations) to derive standard errors and bias corrected accelerated confidence intervals.
Amplified products were used to derive standard curves for quantitative (real-time) RT-PCR.
Amplified products were used to derive standard curves for quantitative RT-PCR (real-time RT-PCR).
To derive standard errors and 95% confidence intervals, we used a bootstrapping procedure in which we repeatedly re-sampled subject observations with replacement and re-estimated the fit [38].
Therefore, it is often to difficult to derive standard errors of the parameter estimates.
5 29 30 We used the delta method to derive standard errors of Wald-type instrumental variable log odds ratios.
What type of methods they used to derive standard errors of the estimates (Efron's bootstrap method?).
Finally, to derive standard errors, we performed a bootstrapping approach for all the strategies by drawing 10,000 samples with replacement and calculating the ICER for each sample.
These Cq values obtained with serial dilutions of target molecules are used to derive standard curves which were in turn used to convert Cq values to molecules.
