History / What's new?
V1.52
-
is a bug fix release
-
in some cases [NEW] created a MDPRO which was invalid
(in the sense that it couldn't be used for further processing)
V1.5
-
moda has now a CATALOG of fit functions which can be browsed,
and edited from within moda. A default catalog comes with the
moda distribution and is stored under the name MDCAT.
-
some minor changes of the user interface within [NEW]
( The matrix editor and the equation writer are no called directly
when [EDIT] has be selected.)
-
This version comes with this new&shiny html documentation.
V1.4
-
improved user interface: the initial values of the parameters canbe
edited in a more convenient way
-
moda does now attach itself to the STAT menu
-
fixed a bug in [GDMF]
V1.3
-
moda can now handle ANY NUMBER of parameters. I.e. if you'd
like to use 213 parameters ... well, then just do it.
-
Changed the menu item [x->F] to [EVMF], since the old name didn't
work in ALG mode. It's ONLY THE NAME that has been changed
-
New menu item: [CNFI] which gives the size of the one-sigma
confidence limit of the model function at x..
-
New menu item: [PCNFI] plots the model function together with the
upper and the lower bound of a specified confidence region.
-
[GMAT] has become [GDMF] since it does now put the data matrix
AND the modelfunction on the stack ... the model function does
contain the current parametervalues
V1.2
-
V1.2 is nearly twice as fast as V1.1
V1.1
There is a HP48 version of moda. With respect to this HP48 version
the
following features are changed/new in MODA V1.1 for the HP49:
-
All the essential subroutines have been recoded from scratch, the
implementationof the Levenberg-Marquardt algorithm has been
changed. This version of modais already somewhat faster than the
HP48 version.
-
[INFO] gives now the covariance matrix in addition to chi^2 and
the corresponding probability.
-
It is no longer necessary to input a DATA-matrix with 3 columns,
2 columnsare sufficient. In this case moda will assume that all the
errors of they-values have the value 1. The fitting procedure is faster
in this case (as compared to the case where a third column has been
entered ).
-
[NEW] does some more checks on the data and the model function.
These new checks are: (1) check whether one of the y-errors is 0,
(2) check whether the model function does contain the variable X.
-
There is a new menu item: MGET, it extracts the data matrixfrom
MDPRO.
-
This version does not create the variable x and/or the parameter
variables.I.e. moda does create only the variables MDPRO, MDD.
(The [PLOT] item doescreate/modify the statistics matrix and the
plotting variables.)
-
Fixed two bugs of the HP48 version of moda. These bugs affected
only the [NEW] item.
