accelstab - New AccelStab Release

AccelStab 2.3.1

This is a minor release that changes the following...

step1down() and step1sample_mvt()

• Replaced sigma with chisq for multi-temperature models
• The residual error standard deviation (sigma) is now sampled from its own distribution rather than being treated as fixed.

step1samplemvt()

• Updated to align with step1_down():
• Added ... (ellipsis) to support optional arguments passed to minpack.lm::nlsLM() during model fitting.

excursion()

• Updated procedure for excursion() to draw from multi-t dist like used in step1down() and step1sample_mvt().

accelstab - New AccelStab Release

AccelStab 2.2.0

This is a minor release which adds extra functionality to existing functions plus a vignette has been added that gives more background to the package.

Enhancements

Vignette

• Added a vignette that gives more information on the background theory of the package.

step1_plot_diagnostic()

• Includes validation data in observed vs predicted and residuals vs predicted scatter plots, if provided.
• Adds a new plot: residuals vs time, color-coded by temperature, and includes validation data points when present.
• Vignette updated to reflect that the function now generates five plots (previously four).

Plotting Functions (step1_plot_CI(), step1_plot_desc(), step1_plot_PI(), step1_plot_pred(), step1_plot_T())

• xlim and ylim now truncate the visible plot area only, without removing data used in the plot.

Bug Fixes

step1_plot_diagnostic()

• Fixed QQ plot to show quantiles for all data, rather than temperature-specific quantiles.

step1_down() and step1_down_basic()

• Added ... to allow passing optional arguments to minpack.lm.
• When reparam = TRUE, now prints a message: default lower bounds are 0, but custom bounds may be specified.
• Fixed issue with Kelvin temperature inputs.

Documentation

• Updated function descriptions across all relevant functions for clarity and completeness.

accelstab - Accelerated Stability Kinetic Modelling

This is the second version of the AccelStab kinetic modelling package, some extra features are added alongside bug fixes.

New features

• step1downrmse() added which allows the user to calculate the root mean squared error for their data and chosen parameters
• step1downdiagnostic() added which allows the user to plot residual diagnostic plots after fitting the model
• step1samplemvt() added which allows the user to draw a chosen number of sample parameters from the multivariate t distribution for their own analyses
• step1_down() now accepts an extra argument validation which sidelines some of the data allowing the user to save it for testing purposes
• step1plotdesc() now accepts an extra argument validation which sidelines some of the data allowing the user to save it for testing purposes

Bug fixes

• When selecting a temperature outside the data set for step1plotT() the colours of the prediction line and the ribbon are now consistent
• When using the argument temppredC within step1_down() no longer are predictions duplicated if the temperature is already in the data
• Issue when no time = 0 rows present in the data and no parms provided to step1_down() now resolved
