• switch from packages multicore and snow to parallel
  • changed behavior of bols(x, intercept = FALSE) when x is a factor: * now the intercept is simply dropped from the design matrix * coding can be specified as usually for factors.
  • changed default for options("mboost_dftraceS") to FALSE, i.e., degrees of freedom are now computed from smoothing parameter as described in B. Hofner, T. Hothorn, T. Kneib, M. Schmid (2011).
  • changed computation of B-spline basis at the boundaries: now also use equidistant knots in the boundaries (per default)
  • improved plot function when dealing with spatial plots (now builds suitable grid based on the observations if no newdata is given)
  • increased default number of subsampling replicates in stabsel to 100
  • [experimental] bmono() now implements constraints at the boundaries of (monotonic) P-splines
  • [experimental] added family Gehan() for rank-based estimation of survival models in an accelerated failure time framework (contributed by Brent Johnson )
