Principle component analysis of TD children's temporal-spatial gait parameters quantified raw gait deviation from typical, normalized to an average standard deviation) Toddle TDI score of 100(10), and calculated for all participants.
The data set was made up of 78,209 records for birth weight with an average value of 41.52 kg and a raw standard deviation of 4.65 kg.
The dataset consisted of 17 069 records for weight at 210 days (W210), with an average value of 266 kg and a raw standard deviation of 52.9 kg.
For example, in order to test the interaction of system quality with direct network externalities we first centered the three variables: (1) system quality of CRM, (2) direct network externalities, and (3) intent to adopt by replacing raw scores with deviation scores.
Their mean and standard deviation raw scores were used to restandardize test scores from the current sample, with a M of 100, SD of 15, and possible range from 55 to 145.
Standardized regression coefficients (with 95% confidence limits) were converted to the original variable scale for ease of interpretation by multiplication with the raw data standard deviation of the target variable within the respective data.
Indeed, four blood flow related features are found to be correlated to both the left and right feet mean stride interval (peak frequency of the R-MCA raw signal, standard deviation of the L-MCA raw signal, both the skewness and kurtosis of the R-MCA envelope signals).
Raw means, standard deviations, as well as between- and within group effect sizes based on completer data are presented in Additional file 1.
In artifact-free epochs of MEG raw data (signal deviations of more than 3.5 pT in the MEG or erroneous button presses on non-target vowels as well as target vowels were excluded), power spectral estimates were derived from Fourier transforms on pairs (overlapping by one half) of 188.75 ms Welch-windowed segments.
Results: The relative deviation of Raw from its personal target was expressed as (measured Raw - target Raw)/target Raw.
