A tag is a keyword or label that categorizes your question with other, similar questions. Using the right tags makes it easier for others to find and answer your question.

 glmm× 223 Generalized Linear Mixed (effects) Models are typically used for modeling non-independent non-normal data (eg, longitudinal binary data). power× 221 Is a property of a hypothesis testing method: the probability of rejecting the null hypothesis given that it is false, i.e. the probability of not making a type II error. The power of a test depends o… kernel-trick× 218 Kernel trick refers to kernel methods in machine learning, such as kernel support vector machine (SVM) or kernel principal components analysis (PCA). It allows to generalize linear techniques to non-l… continuous-data× 217 called continuous if its set of possible values is uncountable, and the chance that it takes any particular value is zero ($\text{P}(X = x) = 0$ for every real number $x$). A … post-hoc× 217 decided upon after the data has been collected, as opposed to "a priori". reliability× 217 said to have a high reliability if it produces similar results under consistent conditions. DO NOT confuse reliability with validity (see tag wiki). group-differences× 215 Group differences broadly refer to statistics which quantify the differences between two or more subpopulations. skewness× 212 Skewness measures (or refers to) a degree of asymmetry in the distribution of a variable. robust× 209 Robustness in general refers to a statistic's insensitivity to deviations from its underlying assumptions (Huber and Ronchetti, 2009). scikit-learn× 208 Machine learning framework for Python. standardization× 208 Shifting and rescaling data to assure zero mean and unit variance. naive-bayes× 208 a simple probabilistic classifier based on applying Bayes' theorem with strong independence assumptions. A more descriptive term for the underlying probability model would … quantiles× 205 The quantiles of a distribution refer to points on its cumulative distribution function. Some common quantiles are quartiles and percentiles. discrete-data× 205 Refers to data generated from a distribution that has a countable sample space. Discrete data may be nominal (e.g. the distribution of race in a sample of individuals) or ordinal (e.g. the number of e… kolmogorov-smirnov× 204 a test for goodness of fit of data to a distribution. It is often used to test whether a variable is normally distributed. exponential× 203 A distribution describing the time between events in a Poisson process; a continuous analogue of the geometric distribution. scales× 202 express measurements, usually ratio, interval, ordinal or nominal scales. posterior× 201 Refers to the probability distribution of parameters conditioned on data in Bayesian statistics. deep-learning× 201 a new area of Machine Learning research concerned with the technologies used for learning hierarchical representations of data, mainly done with deep neural networks (i.e. networks with two or more hi… large-data× 200 'Large data' refers to situations where the number of observations (data points) is so large that it necessitates changes in the way the data analyst thinks about or conducts the analysis. (Not to be … small-sample× 200 Refers to any statistical complication or problem due to having few data. lme4× 199 an R package to fit linear and generalized linear mixed-effects models. causal-inference× 199 Causal inference tries to quantify the effect of a change in $X$ on $Y$ whilst holding constant or eliminating all other relevant factors which might influence this relationship. basic-concepts× 198 biostatistics× 197 The science of statistics applied to the analysis of biological or medical data. curve-fitting× 197 fit curves (as in linear or non-linear regression) to data. kernel-density-estimate× 197 a method of estimating a probability distribution using estimators of a particular form. histogram× 194 a graphical representation of the frequencies of a continuous variable. The variable is divided into bins and a bar is drawn for each bin, proportional to its frequency in the data. gaussian-process× 194 Gaussian processes refer to stochastic processes whose realization consists of normally distributed random variables, with the additional property that any finite collection of these random variables … bayes× 194 Combining probabilities with Bayes' Theorem, especially as used for conditional inference. pattern-recognition× 194 Refers to techniques for classifying data into categories based on similarities (which can either be known previously, or learned). distance-functions× 193 Distance functions refer to functions used for quantifying the notion of distance between members of a set, or between objects. median× 192 the value below which half the data or probability distribution lies - when the sample size is odd, the median is the 'middle' value of an ordered sample. validation× 192 the process of assessing whether the results of an analysis are likely to hold outside of the original research setting. DO NOT use this tag for discussing validity of a measurement or… lognormal× 191 the distribution of a random variable whose logarithm has a normal distribution. distance× 191 Measure of distance between distributions or variables, such as Euclidean distance between points in n-space.
