Exempel på hur man kan använda NONPARAMETRIC i en mening

• Regarding nonparametric (and semiparametric) models, Sir David Cox has said, "These typically involve fewer assumptions of structure and distributional form but usually contain strong assumptions about independencies".
• It is a nonparametric test that tests the null hypothesis that the medians of the populations from which two or more samples are drawn are identical.
• The Mann–Whitney U test / Wilcoxon rank-sum test is not the same as the Wilcoxon signed-rank test, although both are nonparametric and involve summation of ranks.
• The synthesis can also be performed in multiresolution, such as through use of a noncausal nonparametric multiscale Markov random field.
• MDR was designed specifically to identify nonadditive interactions among discrete variables that influence a binary outcome and is considered a nonparametric and model-free alternative to traditional statistical methods such as logistic regression.
• It may appear at first that semiparametric models include nonparametric models, since they have an infinite-dimensional as well as a finite-dimensional component.
• A commonly used likelihood-based model to accommodate to a censored sample is the Tobit model, but quantile and nonparametric estimators have also been developed.
• Within the analysis module, analytic routines include t-tests, ANOVA, nonparametric statistics, cross tabulations and stratification with estimates of odds ratios, risk ratios, and risk differences, logistic regression (conditional and unconditional), survival analysis (Kaplan Meier and Cox proportional hazard), and analysis of complex survey data.
• His most well known contributions are: (i) the formalisation of the econometrics of realised volatility, which nonparametrically estimates the volatility of asset prices, (ii) the introduction of the auxiliary particle filter (signal extraction), (iii) the nonparametric identification of jumps in financial economics, through multipower variation, (iv) stochastic volatility models based on non-Gaussian Ornstein-Uhlenbeck processes, known as 'Barndorff-Nielsen-Shephard' models.
• More recently, nonparametric methods such as the Burgman and Fox's alpha-hull and Getz and Wilmers local convex hull have been used.
• StatPlus is a software product developed by AnalystSoft for basic univariate and multivariate statistical analysis (MANOVA, GLM, Latin squares), as well as time series analysis, nonparametric statistics, survival analysis and statistical charts including control charts.
• He has also made numerous novel contributions to nonparametric statistics (obtaining the surprising result that cross-validation does not suffer from the curse of dimensionality for consistent estimation of the embedding dimension of a dynamical system), Markov chain modelling (with application to weather data), reliability, non-stationary time series analysis (in both the frequency domain and the time domain) and wavelets.
• Marshall, Inequalities: Theory of Majorization and its Applications (1979) and Life distributions: Structure of nonparametric, semiparametric, and parametric families (2007).
• It publishes peer-reviewed work pertaining to new statistical tests and the comparison of existing statistical tests; bootstrap, Jackknife, and resampling methods; nonparametric, robust, permutation, exact, and approximate randomization methods; and statistical algorithms, pseudorandom number generators, and simulation techniques.
• They reached two different conclusions of the entrainment model with Aschoff supporting a parametric entrainment concept (gradual entrainment throughout the day) and Pittendrigh supported a nonparametric entrainment concept (entrainment is sudden and once a day).
• A 2011 article in the Journal of Econometrics, "The impact of the National School Lunch Program on child health: A nonparametric bounds analysis", affirmed the nutritional advantages of the Healthy, Hunger-Free Kids Act but found that "children in households reporting the receipt of free or reduced-price school meals through the National School Lunch Program are more likely to have negative health outcomes than observationally similar nonparticipants".
• In the article, the unknown marginal distribution estimators and the copula dependence parameter estimators are given in Xiaohong Chen and Yanqin Fan's studies of copula-based semiparametric stationary Markov time series models that contains nonparametric marginal distributions and parameterized copulas.
• Interval Predictor Models are sometimes referred to as a nonparametric regression technique, because a potentially infinite set of functions are contained by the IPM, and no specific distribution is implied for the regressed variables.
• Multilevel regression can be replaced by nonparametric regression or regularized prediction, and poststratification can be generalized to allow for non-census variables, i.
• He has also developed original methods for Bayesian inference in Tobit censored responses, discretely observed diffusions, univariate and multivariate ARMA processes, multivariate count responses, causal inference, hierarchical models of longitudinal data, nonparametric regression, and unconditional and conditional moment models.
