paleoTS 0.6-2

Bug fix

• corrected a bug, reported by N. Hohmann, in test.var.het() so that it gracefully handles a situation where some sample variances are zero.

Minor changes

• Added a warning message to fit3models() and fit4models() that cautions against interpreting model support for very short sequences.

paleoTS 0.6.1

Major changes

• added capacity to fit many models using state-space models (SSMs) and the Kalman filter
• model-fitting functions now return the convergence code from optim()
• added additional information to paleoTSfit class, which also has a new print method to show an informative summary of these objects
• improved default setting for all optimization functions that improves convergence behavior
• function akaike.wts() is now documented and exported

Minor changes and bug fixes

• the plot method for paleoTS objects now allows the user more control, including specifying axis labels
• bug fix for fitMult() that previously wouldn’t use the hess argument even when specified
• standardized how bounds are handled in L-BFGS-B optimization for non-negative parameters
• bug fix for the function sub.paleoTS(), which returned an incorrect start.age in some situations

These binaries (installable software) and packages are in development.
They may not be fully stable and should be used with caution. We make no claims about them.
