In mfp: Multivariable Fractional Polynomials

mfp 1.5.4

• Fixed a bug where variables with nested names were incorrectly excluded from the model.

mfp 1.5.3

• Added term predictions including first and second derivatives.
• Rewrote vignette as an .Rmd file and added a terms prediction example.
• Corrected the use of offsets in glm models.
• Changed rescale default: Now, by default `rescale = FALSE'.

mfp 1.5.2

• Minor corrections (Vignette float options error; function namespace).

mfp 1.5.1

• Minor corrections (Vignette keywords updated).

mfp 1.5.0

• New maintainer; 'vignettes' directory added.

mfp 1.4.9

• Minor corrections in fp.rescale.

mfp 1.4.8

• Call of final fitted glm/coxph model corrected (parent frame was missing).
• plot.mfp (temporarily) removed.
• Correction of rescaling procedure of log trafos in fp.rescale.

mfp 1.4.7

• summary.mfp added to avoid problems calling summary directly on mfp object.

mfp 1.4.6

• Minor corrections.

mfp 1.4.5

• Minor corrections of component 'fit'.

mfp 1.4.4

• predict.mfp added.

mfp 1.4.3

• Corrected in object$fit: Use quadratic in ln(X) when powers=(0,0).

mfp 1.4.2

• Minor corrections to use 'subset' properly and to allow to ignore 'data'.

mfp 1.4.0

• Data set 'GBSG' from the JRSS-A paper replaced by its Stata version.
• 'rescale' argument added to function call.
• 'keep' argument added to function call.
• Verbose output now shows also transformation functions of covariates.

mfp 1.3.2

• Scaling of variables is added to model fit used for output component 'fit'.

mfp 1.3.1

• Output corrected for FP2 with equal powers.
• mfp now works even without any FP call.
• New argument 'method' to select method for tie handling in Cox models.
• Vignette updated.

mfp 1.3.0

• Changes in the primary ordering of variables.
• Scaling changed.
• Likelihood ratio tests are now used for all selections.
• Plot of functional form corrected.
• Print function corrected.
• Value of mfp fit has new component `fit'.

mfp 1.2.2

• plot.mfp changed: new argument `var'.
• New dataset `bodyfat' to be used as an example for linear regression.
• Vignette included.

mfp 1.2.1
