Vector Space Model: A vector space model is a mathematical model used in statistics, data mining, and machine learning to describe a set of objects in terms of their attributes and relationships between them.
Definition of Independent Variable An independent variable is a variable that is manipulated by the experimenter in a scientific study. It is typically one factor that is changed while all other factors are kept constant. What is an Independent Variable used for? An independent variable is a type of variable used in statistical models and…
Ad Hoc Analysis is an exploratory analysis technique used to uncover patterns or relationships in a dataset. Often times this work is performed “Ad Hoc” or “On The Fly”… meaning it it done in the moment.
Definition of Time Series Data A time series is a sequential set of data points, typically measured at successive points in time. Time series analysis is the process of analyzing time series data in order to identify patterns and forecast future values. Time series data can be used to measure and predict changes in everything…
Definition of Mode Mode: Mode is a statistical measure of the typical value of a data set. It is calculated by taking the sum of the data values and dividing by the number of data points. Mode is most useful when dealing with nominal data. How is Mode used? Mode is a central measure of…
Definition of Normalization Normalization: Normalization is the process of standardizing data so that it has a consistent meaning across different data sets. This can be done by ensuring that all values in a data set are within a certain range, or by converting all data to a single numerical representation. Normalization can make it easier…
