demography v0.999 (30 July
2010)
e0 rewritten to allow calculation from coherentfdm results, and to
correct the computation of prediction intervals. These are now done
using simulations which are much slower than what was done previously,
but they are correct (unlike in previous versions). Set the argument
PI=TRUE to compute prediction intervals.
tfr rewritten to correct the computation of prediction intervals.
These are now done using simulations which are much slower than what was
done previously, but they are correct (unlike in previous versions). Set

smooth.demogdata slightly modified to give better results.
Bug fixes in various functions.
Smooth.demogdata handles age-??grouping better.
Smooth.demogdata no longer crashes if all age groups have zero
population in a year.
demography v0.95
Most data have now been taken out of the package (as it is now
publicly available). The only data sets in the demography package are
fr.mort (French mortality) and aus.fert (Australian fertility).
The package now handles fertility, mortality and migration data. The
basic data class is ?demogdata? and demogdata$type indicates the type of
demographic data.
Many functions have been revised to handle the new data structures.
However, I?ve tried to keep the calling syntax the same. If existing
code no longer works, check the help files first.
fmm has been renamed as fdm as it now fits functional demographic
models (and not only functional mortality models).
read.mortality has been renamed as read.demogdata. Similarly, other
functions of the form xxx.mortality are now called xxx.demogdata.
smooth.demogdata now handles various types of smoothing and
smoothing constraints. See the help file for details. It tries to do
something appropriate depending on the type of data passed. At the
moment, it only handles mortality and fertility data.
I?ve added tfr to compute total fertility rates, and isfe to compute
the Integrated Squared Forecast Error for different model orders.
The documentation has been revised in many places, and several
references added.
All these changes have almost certainly introduced new errors
