logbin 2.0.5

• Fixed reparameterisation for factor variables in method = “cem” (@jakobschoepe, #3)
• Implemented a more efficient approach to parameter expansion (using the transformation matrix).
• When using the parameter expansion approach, check convergence of the reduced parameter vector. As an indirect result, the conv.test function is no longer exported.
• Fixed error in logbin if offset provided
• Implement coeftrace via turboEM::turboem argument keep.paramval, to avoid taking a different path when it is turned on (#5)

logbin 2.0.4

• Added citation to Journal of Statistical Software article.

logbin 2.0.3

• Added coeftrace argument to logbin.control, such that coefficient history can be obtained for method = "em" and method = "cem".

logbin 2.0.2

• Changed logbin.ab so that outer.iterations can be set by control$maxit in the call to logbin, and maxit (inner iterations) is set by control.method$maxit.
• logbin now returns contrasts, qr, R and effects components, so associated glm S3 methods (e.g. influence, plot) will work.
• weights component returned is the IRLS working weights at the last iteration, for consistency with glm (even though these are not actually used except with method = "glm").
• plot.logbin.smooth with type = "diagnostics" will plot the model diagnostics usually produced by plot.lm.
• plot.logbin.smooth will allow extra parameters (e.g. col, ylim) to be passed.

logbin 2.0.1

• (Had to increment version number to satisfy CRAN check after correcting an error)

logbin 2.0

• method option added: fit using glm, glm2, adaptive barrier, CEM or single EM algorithm with overparameterised model
• accelerate option added: use turboEM methods to speed up convergence
• (Minor change) Corrected the definition of boundary

logbin 1.2

• Minor documentation changes (e.g. updated references)

logbin 1.1

• Very minor documentation changes

logbin 1.0

• Added na.action argument to logbin() and smooth.logbin()
