Windowed Aggregation: Windowed aggregation is the process of computing a statistic over a fixed-size window of data. The window slides along the data set, taking a fixed number of values from the start of the set and computing the statistic for each one. This can be done with any type of data, but is particularly useful for time series data.
Definition of Exact p-value Exact p-value: The Exact p-value is the probability of obtaining a test statistic at least as extreme as the one that was actually observed, assuming that the null hypothesis is true. What is Exact p-value used for? Exact p-values are used to help assess the strength of evidence for a hypothesis…
Definition of Regression Regression: Regression is a technique used to model relationships between variables. It can be used to predict future values based on past values.
Definition of Type II Error Type II error: A type II error, also known as a false negative error, is the incorrect acceptance of a false null hypothesis.
Definition of Embedding Embedding: Embedding is a technique used in machine learning for representing high-dimensional data in a low-dimensional space. It is used to improve the performance of algorithms by reducing the number of parameters that need to be estimated or optimized. This is often done in order to improve the efficiency of machine learning…
Definition of Oblique Sampling Oblique Sampling: Oblique sampling is a type of non-random sampling technique. It is used when the researcher wants to study a specific population but does not have access to all members of that population. Oblique sampling involves selecting units for the study in a way that is not completely random. The…
