• 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 )
