Accurate and timely change detection of Earth’s surface features is extremely important for understanding relationships and interactions between people and natural phenomena. Many traditional methods ...
STATISTIC TESTS AIDED MULTI-SOURCE DEM FUSION
DEM Fusion Blunder Detection Statistic Test
2016/11/15
Since the land surface has been changing naturally or manually, DEMs have to be updated continually to satisfy applications using the latest DEM at present. However, the cost of wide-area DEM producti...
A New Test Statistic for Key Recovery Attacks Using Multiple Linear Approximations
multiple linear cryptanalyis LLR statistic chi-squared statistic
2016/4/26
The log-likelihood ratio (LLR) test statistic has been proposed in the literature for performing statistical analysis of attacks on block ciphers. A limitation of the LLR test statistic is that its ap...
Joint Data and Key Distribution of the Linear Cryptanalysis Test Statistic and Its Impact to Data Complexity Estimates of Multiple/Multidimensional Linear and Truncated Differential Attacks
multidimensional linear attack zero-correlation linear
2015/12/22
The power of a statistical attack is inversely proportional to
the number of plaintexts necessary to recover information on the encryption
key. By analyzing the distribution of the random variables ...

A Joint Test Statistic Considering Complex Wishart Distribution Characterization of Temporal Polarimetric Data
polarimetric SAR temporal analysis tracking change detection complex wishart
2015/11/20
Polarimetric data of distributed scatterers can be fully characterized by the (3 ￡ 3) Hermitian positive definite matrix which follows a complex Wishart distribution under Gaussian assumption. A...
On the asymptotic distribution of the Moran I test statistic withapplications
Moran I test Spatial autocorrelation Asymptotic distribution Central limit theorem
2015/9/24
By far, the most popular test for spatial correlation is the one based on Moran’s (1950) I test statistic. Despite this, the available results in the literature concerning the large sample distributio...
In recent years, the kappa coefficient of agreement has become the de facto standard for evaluating
intercoder agreement for tagging tasks. In this squib, we highlight issues that affect κ and ...
TESTING FOR INDEPENDENCE IN A TWO-WAY TABLE: NEW INTERPRETATIONS OF THE CHI-SQUARE STATISTIC
Classic chi-square distribution independent statistics dimension
2015/7/14
The classical chi-square test for independence in a two-way contingency
table often rejects the independence hypothesis at an extremely small signif-
icance level, particularly when the sample siz...

An Application of a Variable Window Discrete Scan Statistic in Molecular Biology
Amino acids Moving sums Product-type approximation Scan statistic
2015/3/18
In this article a variable window discrete scan statistic is introduced for a
conditional scan statistic. This statistic is used to test the null hypothesis that the
observations are randomly distri...
