⚠️There's a newer version (2.5.1) of this package.Take me there.

cir (version 2.5.0)

Centered Isotonic Regression and Dose-Response Utilities

Description

Isotonic regression (IR) and its improvement: centered isotonic regression (CIR). CIR is recommended in particular with small samples. Also, interval estimates for both, and additional utilities such as plotting dose-response data. For dev version and change history, see GitHub assaforon/cir.

Functions in cir (2.5.0)

Piecewise-linear local slopes given a (non-strictly) monotone x-y sequence

Isotonic Regression, Centered Isotonic Regression, and Dose-Response Utilities

Backend utility to calculate inverse (dose-finding) intervals, using local inversion and the Delta method

Analytical ordered-binary-Y confidence intervals, using the Morris (1988) algorithm

"Old School" isotonic-regression point estimates, with flexible dose-response input

Centered-isotonic-regression (CIR) point estimation

Inverse (dose-finding) point estimate (e.g., estimating a percentile)

Backend utility to calculate analytical CIR/IR interval estimates, given the point estimates

Constructor functions and class-checking functions for DRtrace and doseResponse classes

Shrinkage fix to mitigate bias in observed rates, under adaptive dose-finding designs

Plotting Methods for DRtrace, doseResponse Objects
