- Fix bug triggered by new - funargument in- Bernstein_basis.
Changes in Version 1.2-4 (2025-09-23)
- Allow prior transformations more general than - login- Bernstein_basisvia its new- funargument.
- Fix problem when computing the second derivatives of Bernstein polynomials after log-transformation. 
Changes in Version 1.2-3 (2025-05-09)
- repto- rep_len.
Changes in Version 1.2-2 (2025-01-29)
- Switch from coneproj to quadprog in - ?Bernstein_basis.
Changes in Version 1.2-1 (2025-01-17)
- Allow to keep unused levels in - as.basis.formula.
Changes in Version 1.2-0 (2024-05-21)
- New - cyclic_basis()for modelling seasonal effects.
Changes in Version 1.1-4 (2023-05-16)
- Bernstein_basis(..., ui = c("increasing", "zerointegral")came with incorrect constraint matrix.
Changes in Version 1.1-3 (2022-05-25)
- Bernstein_basis(..., ui = "zerointegral")came with incorrect constraint matrix.
Changes in Version 1.1-2 (2022-01-14)
- Allow coefficients in matrix form. 
Changes in Version 1.1-1 (2021-11-12)
- Add convexity and concavity constraints to polynomials in Bernstein form. 
- Add toy example demonstrating constrainted curve estimation to - ?Bernstein_basis.
Changes in Version 1.1-0 (2021-03-09)
- More infrastructure for - as.basisto return a- Matrixobject for ordered factors.
Changes in Version 1.0-7 (2020-02-13)
- Update citation info. 
Changes in Version 1.0-6 (2019-10-05)
- Change name of parameter in - intercept\_basisto- (_Intercept_); this helps to detect intercepts originating from other calls to- model.matrix..
Changes in Version 1.0-5 (2019-06-20)
- Make sure - bounds[1]is positive if- log_first = TRUE.
- Correct behaviour outside support when - log_first = TRUE.
Changes in Version 1.0-4 (2019-02-25)
- model.matrixhas- constrastsattribute where appropriate.
Changes in Version 1.0-3 (2019-01-16)
- Bernstein(log()) is possible with new - log_firstargument.
- Fix > length 1 issues. 
Changes in Version 1.0-2 (2018-09-17)
- Constrain Bernstein to zero second derivative at the support when linear extrapolation shall be used. This avoids ugly bumps in the corresponding densities in mlt. 
Changes in Version 1.0-1 (2018-03-27)
- Replace - rBindby- rbindas requested by MM.
Changes in Version 1.0-0 (2018-03-07)
- A paper describing version 1.0-0 of the mlt, basefun, and variables packages was accepted for publication in the Journal of Statistical Software 2018-03-05. 
- Documentation updates. 
Changes in Version 0.0-40 (2018-02-23)
- nparmsometimes generated data with sanitised variable names, we don't want this to happen.
- Allow positive increasing Bernstein polynomials. 
Changes in Version 0.0-39 (2017-12-18)
- Add - intercept_basis, ie an intercept only model matrix.
Changes in Version 0.0-38 (2017-05-15)
- model.matrix.cbind_basescan now deal with lists as- newdataargument (given appropriate dimensions in- dim).
Changes in Version 0.0-37 (2017-04-04)
- Deal with integer variables when - sumconstr = TRUE.
- Remove unnecessary warning when - sumconstr = TRUEand- negative = TRUE.
Changes in Version 0.0-36 (2017-03-01)
- Register C routines. 
Changes in Version 0.0-35 (2017-02-14)
- Fix bug in - predictwhen- newdatawas a data frame.
Changes in Version 0.0-34 (2016-12-14)
- Fix bug in - predictwhen- newdatawas a list. The ordering of the resulting array may have been incorrect under rare circumstances.
Changes in Version 0.0-33 (2016-09-12)
- Approximate Bernstein polynomial f outside its - support(l, u) by a linear function f(u + x) = f(u) + f'(u) * (u - x), now also for- deriv > 0(- maxderivargument in- model.matrix.Bernstein_basis. The default (linear extrapolation for- deriv = 0only) did not change.
Changes in Version 0.0-32 (2016-05-31)
- Contraints in - log_basiswere potentially wrong.
Changes in Version 0.0-31 (2016-04-25)
- log_basishas better checks for positivity of the variable to be log-transformed.
Changes in Version 0.0-30 (2016-02-19)
- The basefun package was first published on CRAN.
