The simulation results begin to diverge around the 5th data point (10 July) and converge again around the 17th data point (22 July).
The simulation results for different parameter settings begin to diverge on the 5th and converge on the 17th data points.
That is, the percentages of blocks rotated, to 1° are summed up and tabulated in the 1st data row, the percentages of blocks rotated, to 2° are summed up and tabulated in the 2nd data row, and so on.
P* are the nominal (true) values, P(1) the values based on the 1st data set, P(1)+(2) based on the 1st, 2nd data sets together, P(1)+(2)+(3) based on the 1st, 2nd, and 3rd data sets, P(1)+…+(4) based on the 1st to 4th data sets, and P(1)+…+(5) based on the 5 data sets, respectively.
In this method, the 2nd data entry operator is authorized to take decisions about correctness of the data.
Figure 1A (upper panel) shows the angles between the columns of the state sensitivity matrix by fitting to the 1st data set.
In order to have a good behavior even with small number of strata, it is sufficient to start from a higher percentile such as the 20th (data not shown).
Data collection in all three states occur at baseline (prior to the first lesson of the HT or the control intervention), at post (after completion of the eighth lesson, after 3 months for controls), and at 6 months after completion of the 2nd data collection for both the intervention and control groups.
We sought to use the INTERGROWTH-21st data to develop centiles for the distribution of GA for CRL values between 15 mm and 100 mm.
A sample size of 100 was chosen as it represented the average number of CRL observations for each GA in the INTERGROWTH-21st data and is large enough to remove effects of sampling variation.
