Data were averaged based on the quantity of data points available to account for unavailable data.
When necessary, the quantity of data points was broadened by conducting a linear interpolation between two known points in the dataset.
Fig. 11 Accuracy comparison of Distributed Scatterer (DS) and Persistent Scatterer (PS), acc. to (Schindler 2014) Fig. 12 Comparison of quantity (number of data points) as functions of space and time corridors, acc. to (Schindler 2014).
It is amazing but at the same time frightening what massive quantities of spatio-temporal data points from mobile phones can tell us about ourselves, our lives, and our society in general.
"Simply put, there is neither a sufficient quantity, nor more importantly quality, of data points to gain real benefit from an algorithmic analysis," he states.
Here, we generate a synthetic data (i.e. wave packet) that a time series of data at a certain altitude z by a vertical sounding can be expressed as (for example, Kuo et al., 1993) (1 where N is the recorded quantity, n is the number of data points, C, ω j, and k j are the amplitude, angular frequency, and vertical wave number of the jth harmonic, respectively.
Neither of these quantities show any suspicious outliers (that is, data points that are very far from the mean behaviour), and they agree with human observations of swarm size and the typical travel times of midges through the swarm volume.
Because of the large number of data points (five samples per second), both quantities were interpolated on a 6-s sub-sampled grid.
The amount of smoothing is calibrated by the size of the neighborhood, or percentage of the data points, over which averaging is done; a quantity known as span.
The quantity of data (expressed by means of the number of experimental data points) as well as the positioning of these data in time have a substantial influence on model parameter uncertainty.
