5.4.0.0

Identical to version 5.4 on CRAN.

5.3.1.3

Eliminate spurious warnings arising on certain platforms.

5.3.1.2

Release to eliminate warnings on certain platforms.

5.3.1.0

Changes in pomp version 5.3.1:

• stew now returns timing information by default.

5.2.5.1

Changes in pomp version 5.2.5:

• The new option on_load allows one to specify a C snippet that will be executed at the time the C snippet library is loaded.
• Internally, the userdata are made available via calls to pompLoad rather than within each call to a pomp workhorse.

5.2.4.3

• The data frames returned by cond_logLik and eff_sample_size when format="data.frame" have been improved. In particular, they contain (as variable time) the times (rather than the index of the time vector as before).
• Changes to the report generated by spy.
• Some documentation improvements.

5.2.3.4

Changes in pomp version 5.2.3:

• The manual pages have been reorganized, with improved cross-linking.
• A bug in filter_traj etc. arising when not all state variables have names was fixed.

5.2.2.3

• This version adds the new basic component dinit for evaluating the probability density function of the initial-state distribution. There is a corresponding workhorse function, dinit().

• The constructor pomp now takes the optional argument nstatevars, which can be used to increase the dimension of the latent state-vectors created by rinit. By default, nstatevars = length(statenames), and nstatevars can only be used to increase, not to decrease, the dimension of the latent state process. Moreover, nstatevars has no effect if the rinit basic component is furnished as an R function.

• Name checking on internally-created vectors and arrays is less strict than previously. In particular, it is possible to have variables without names (i.e., "").

5.2.1.0

Changes in pomp version 5.2.1:

• reulermultinom now returns NA rather than NaN, in keeping with the behavior of rbinom. Thanks to John Drake for calling attention to this issue.

5.1.1.3

A bug in stew resulting in namespace conflicts has been repaired.
