Data Analysis Expressions (DAX) is the native formula and query language for Microsoft PowerPivot, Power BI Desktop and SQL Server Analysis Services (SSAS) Tabular models. DAX includes some of the functions that are used in Excel formulas with additional functions that are designed to work with relational data and perform dynamic aggregation .
Matching is a statistical technique that evaluates the effect of a treatment by comparing the treated and the non-treated units in an observational study or quasi-experiment (i.e. when the treatment is not randomly assigned).
Longest prefix match (also called Maximum prefix length match) refers to an algorithm used by routers in Internet Protocol (IP) networking to select an entry from a routing table. [ 1 ] Because each entry in a forwarding table may specify a sub-network, one destination address may match more than one forwarding table entry.
A plot showing silhouette scores from three types of animals from the Zoo dataset as rendered by Orange data mining suite. At the bottom of the plot, silhouette identifies dolphin and porpoise as outliers in the group of mammals. Assume the data have been clustered via any technique, such as k-medoids or k-means, into clusters.
Θ is models posterior distribution, are samples from posterior, and i iterates over training data. In other words, in Bayesian statistics the posterior is represented by list of samples from it. WAIC penalty is then the variance of predictions among these samples, calculated and added for each datapoint from dataset.
A maximal unique match or MUM, for short, is part of a key step [1] in the multiple sequence alignment of genomes in computational biology. Identification of MUMs and other potential anchors is the first step in larger alignment systems such as MUMmer. Anchors are the areas between two genomes where they are highly similar.
Record linkage (also known as data matching, data linkage, entity resolution, and many other terms) is the task of finding records in a data set that refer to the same entity across different data sources (e.g., data files, books, websites, and databases).
The match also has a waterproof coating (which often makes the match more difficult to light), and often storm matches are longer than standard matches. As a result of the combustible coating, storm matches burn strongly even in strong winds, and can even spontaneously re-ignite after being briefly immersed in water.
