Abstract:
This article proposes a strategy for the visual characterization of power quality in big data analysis contexts, culminating in the development of a visualization tool based on higher-order statistics, which exhibits an efficiency between 83.33% and 100% in detecting 50 Hz synthetic and real-life simple and hybrid events, showing its significant potential for real-world applications marked by non-linear loads and non-Gaussian behaviors and surpassing the detection of traditional tools such as boxplot by up to 50%.

Abstract. Satellite remote sensing has gained a key role for vegetation mapping distribution. Given the availability of multi-temporal satellite data, seasonal variations in vegetation dynamics can be used trough time series analysis for vegetation distribution mapping. These types of data have a very high variability within them and are subjected by artifacts. Therefore, a pre-processing phase must be performed to properly detect outliers, for data smoothing process and to correctly interpolate the data.

Abstract The data analyst needs to be able to collect information in a compact form. An analyst cannot look at a set of a thousand values on a value-by-value basis.

In addition to the simple average value, which statisticians call the mean, alternatives are presented that reduce the influence of any atypical values. In the same way, while the simplest measure of summarising the spread of data values is the range, more useful measures, that take account of all the data values

The rules for choosing the right graph are less hard and fast than those for choosing the right test.

This approach is based off of a normal distribution which in reality very rarely occurs with the condition indicators of interest. Instead the data follows other distributions that tend to be heavily right skewed with long tails. This approach is also highly susceptible to inflation caused by an unpredictable number of faulted points within the data set.
