bdsmatrix

cran
99.99th

Percentile

This is a special case of sparse matrices, used by coxme.

coxme

cran
99.99th

Percentile

Cox proportional hazards models containing Gaussian random effects, also known as frailty models.

deming

cran
99.99th

Percentile

Generalized Deming regression, Theil-Sen regression and Passing-Bablock regression functions.

noweb

cran
99.99th

Percentile

The noweb system for source code, implemented in R.

survival

cran
99.99th

Percentile

Contains the core survival analysis routines, including definition of Surv objects, Kaplan-Meier and Aalen-Johansen (multi-state) curves, Cox models, and parametric accelerated failure time models.

RNASeqPower

bioconductor
99.99th

Percentile

RNA-seq, sample size

attribrisk

cran
99.99th

Percentile

Estimates population (etiological) attributable risk for unmatched, pair-matched or set-matched case-control designs and returns a list containing the estimated attributable risk, estimates of coefficients, and their standard errors, from the (conditional, If necessary) logistic regression used for estimating the relative risk.

date

cran
99.99th

Percentile

Functions for handling dates.

DescTools

cran
99.99th

Percentile

A collection of miscellaneous basic statistic functions and convenience wrappers for efficiently describing data. The author's intention was to create a toolbox, which facilitates the (notoriously time consuming) first descriptive tasks in data analysis, consisting of calculating descriptive statistics, drawing graphical summaries and reporting the results. The package contains furthermore functions to produce documents using MS Word (or PowerPoint) and functions to import data from Excel. Many of the included functions can be found scattered in other packages and other sources written partly by Titans of R. The reason for collecting them here, was primarily to have them consolidated in ONE instead of dozens of packages (which themselves might depend on other packages which are not needed at all), and to provide a common and consistent interface as far as function and arguments naming, NA handling, recycling rules etc. are concerned. Google style guides were used as naming rules (in absence of convincing alternatives). The 'camel style' was consequently applied to functions borrowed from contributed R packages as well.

distcomp

cran
99.99th

Percentile

Implementing algorithms and fitting models when sites (possibly remote) share computation summaries rather than actual data over HTTP with a master R process (using 'opencpu', for example). A stratified Cox model and a singular value decomposition are provided. The former makes direct use of code from the R 'survival' package. (That is, the underlying Cox model code is derived from that in the R 'survival' package.) Sites may provide data via several means: CSV files, Redcap API, etc. An extensible design allows for new methods to be added in the future. Web applications are provided (via 'shiny') for the implemented methods to help in designing and deploying the computations.

fortunes

cran
99.99th

Percentile

A collection of fortunes from the R community.

glmBfp

cran
99.99th

Percentile

Implements the Bayesian paradigm for fractional polynomials in generalized linear models, described by Held, Gravestock, Sabanes Bove (2015) <doi:10.1214/14-STS510>. See package 'bfp' for the treatment of normal models.

ipred

cran
99.99th

Percentile

Improved predictive models by indirect classification and bagging for classification, regression and survival problems as well as resampling based estimators of prediction error.

gbm3

github
99.99th

Percentile

Extensions to Freund and Schapire's AdaBoost algorithm and Friedman's gradient boosting machine. Includes regression methods for least squares, absolute loss, t-distribution loss, quantile regression, logistic, Poisson, Cox proportional hazards partial likelihood, AdaBoost exponential loss, Huberized hinge loss, and Learning to Rank measures (LambdaMART).

rpart

cran
99.99th

Percentile

Recursive partitioning for classification, regression and survival trees. An implementation of most of the functionality of the 1984 book by Breiman, Friedman, Olshen and Stone.
