# 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()`
