Epidemiology has a long history of studying factors that affect the variability of the incidence or mortality of infectious and chronic diseases. Among those factors, geographical or spatial variations of health outcomes have played a crucial role in evaluating health care distribution and performance. Spatial variation in health outcomes has also provided evidence of patterns of dependence and level of noise in the data. More recently, time-series analyses have been used to examine the manner in which health variables vary over time. Spatiotemporal analyses have the additional benefits over purely spatial or time-series analyses because they allow the investigator to simultaneously study the persistence of patterns over time and illuminate any unusual patterns. The inclusion of space-time interaction terms may also detect data clustering that may be indicative of emerging environmental hazards or persistent errors in the data recording process.
February 26, Software Open Access. This online application implements statistical methods to analyse spatio-temporal data considering lattice data to describe the space. Once the different data sources have been merged within the application using specific index variables that identifies space and temporal resolution to be used in the analysis and for which information have been recorded, an exploratory analysis using descriptive statistics over space and time can be performed. The exploratory analyses provide the user the possibility to estimate local statistics such as: Moran's I and Geary's C, which could aid to recognize potential clusters and hotspots. Smoothed predictions over space and time can be calculated and visualized using ordinary kriging. Furthermore, two models have been also implemented, considering the binomial nature of the response Logistic regression models.

Visualization Cube: Modeling Interaction for Exploratory Data Analysis of Spatiotemporal Trend Information Abstract: This paper proposes the visualization cube for modeling interaction in exploratory analysis of spatiotemporal trend information. Recent growth of the Web has brought us various type of information, among which trend information is one of the important information, because it is crucial for our decision making. Although interactive information visualization system is useful for supporting exploratory data analysis of trend information, the design of such systems tends to depend on the idea of each designer. It is expected that establishing adequate interaction model will contribute to the design of those systems.
Exploratory data analysis EDA is about detecting and describing patterns, trends, and relations in data, motivated by certain purposes of investigation. As something relevant is detected in data, new questions arise, causing specific parts to be viewed in more detail. So EDA has a significant appeal: it involves hypothesis generation rather than mere hypothesis testing. The authors describe in detail and systemize approaches, techniques, and methods for exploring spatial and temporal data in particular. They start by developing a general view of data structures and characteristics and then build on top of this a general task typology, distinguishing between elementary and synoptic tasks. This typology is then applied to the description of existing approaches and technologies, resulting not just in recommendations for choosing methods but in a set of generic procedures for data exploration. Professionals practicing analysis will profit from tested solutions — illustrated in many examples — for reuse in the catalogue of techniques presented.
In statistics , exploratory data analysis is an approach to analyzing data sets to summarize their main characteristics, often using statistical graphics and other data visualization methods. A statistical model can be used or not, but primarily EDA is for seeing what the data can tell us beyond the formal modeling or hypothesis testing task. Exploratory data analysis was promoted by John Tukey to encourage statisticians to explore the data, and possibly formulate hypotheses that could lead to new data collection and experiments. EDA is different from initial data analysis IDA ,  which focuses more narrowly on checking assumptions required for model fitting and hypothesis testing, and handling missing values and making transformations of variables as needed.

Стратмор в отчаянии нажал на кнопку просмотра. ОБЪЕКТ: ЭНСЕЙ ТАНКАДО - ЛИКВИДИРОВАН ОБЪЕКТ: ПЬЕР КЛУШАР - ЛИКВИДИРОВАН ОБЪЕКТ: ГАНС ХУБЕР - ЛИКВИДИРОВАН ОБЪЕКТ: РОСИО ЕВА ГРАНАДА - ЛИКВИДИРОВАНА… Список на этом не заканчивался, и Стратмора охватил ужас. Я смогу ей объяснить.
Он еще раз сжал его руку, но тут наконец подбежала медсестра. Она вцепилась Беккеру в плечо, заставив его подняться - как раз в тот момент, когда губы старика шевельнулись. Единственное сорвавшееся с них слово фактически не было произнесено. Оно напоминало беззвучный выдох-далекое чувственное воспоминание. - Капля Росы… Крик медсестры гнал его прочь. Капля Росы.
И теперь - во что просто не верится - какой-то ни о чем не подозревающий канадский турист держит в своих руках ключ к самому мощному шифровальному алгоритму в истории. Сьюзан набрала полные легкие воздуха и задала неизбежный вопрос: - И где же теперь этот канадец. Стратмор нахмурился: - В этом вся проблема.
