SAS/STAT

SAS/STAT® è un software pensato per rispondere a necessità di analisi specifiche o legate all'impresa nella sua totalità. SAS/STAT® permette di realizzare analisi di varianza, modelli predittivi tradizionali e offre tecniche di visualizzazione statistica e soluzioni puntuali.
Il software presenta un set di tool completi e intuitivi, in grado di rispondere alle necessità analitiche di dati di tutta l'organizzazione.

  • Bayesian analysis:
    • bayesian modeling and inference for generalized linear models, accelerated life failure models, Cox regression models and piecewise exponential models
    • general procedure fits Bayesian models with arbitrary priors and likelihood functions
  • Multivariate analysis:
    • factor analysis / principal components / canonical correlation and discriminate analysis / path analysis / structural equations
  • Survival analysis:
    • comparison of survival distributions / accelerated failure time models / proportional hazards models
  • Psychometric analysis:
    • Multidimensional scaling / conjoint analysis with variable transformations / correspondence analysis
  • Cluster anaylsis:
    • hierarchical clustering of multivariate data or distance data / disjoint clustering of large data sets / nonparametric clustering with hypothesis tests for the number of clusters
  • Non-parametric analysis:
    • non-parametric analysis of variance / exact probabilities computed for many non-parametric statistics
    • Kruskal-Wallis, Wilcoxon-Mann-Whitney and Friedman tests
    • other rank tests for balanced or unbalanced one-way or two-way designs
  • Survey data analysis:
    • sample selection / descriptive statistics and t-tests / linear and logistic regression / frequency table analysis
  • Multiple imputation for missing values:
    • regression and propensity scoring for monotone missing patterns
    • MCMC method for arbitrary missing patterns
    • combine results for statistically valid inferences
  • Study planning:
    • power and sample size application provides interface for computation of sample sizes and characterization of power for t-tests, confidence intervals, linear models, tests of proportions and rank tests for survival analysis
