SAE Unit/area Models and Methods for Estimation in R

Next major update (version 1.4.0)

• New major functions for simulation and using SPDE spatial model and aggregation over grids.
• New datasets on Kenya population map.
• New methods for benchmarking.

Major update (version 1.3.0)

• New SAE functions and vignette.

Major update (version 1.2.0)

• Major expansion for smoothSurvey to implement popular SAE methods. Syntax change to the function.
• Allows smoothDirect and smoothCluster to fit space-only models.
• S3 class output.

Major update (version 1.1.0)

• Major expansion for smoothSurvey to implement popular SAE methods. Syntax change to the function.
• Allows smoothDirect and smoothCluster to fit space-only models.
• smoothSurvey, smoothDirect, and smoothCluster now returns S3 classed objects.

Major update (version 1.0.0)

Version 1.0.0 contains many major updates from the previous versions:

• Major updates to functions.
  • fitGeneric is now smoothSurvey
  • fitINLA is now smoothDirect
  • fitINLA2 is now smoothCluster
  • More extensions in both smoothed direct and cluster level models.
  • Major changes to how temporal models are specified with time.model and st.time.model.
  • More interpretable parameterization of slope and random slopes.
  • More visualization options.
  • Note: Previous function name and argument syntax remain to work as before, but may not receive high priority in maintenance in the future.
• Many minor improvements in functions.
  • Better model summary message.
  • Removed unnecessary function arguments, e.g., geo in various functions.
  • Removed the requirement to repeated specifying Amat, year_label and year_range. Now they are only required in the model fitting stage.
• New vignettes.

Major update (version 0.3.0)

Version 0.3.0 contains some major updates from the previous versions. Some of the substantial changes to existing functions are listed here. For a complete log of changes, see the News section.

• Function name changes
  • countrySummary is now getDirect
  • cuontrySummary_mult is now getDirectList
  • fitspace is now fitGeneric
  • projINLA is now getSmooth
• New functions
  • getDiag: produce diagnostic plots for the fitted model.
  • getAdjusted: produce adjusted estimates for a fitted model.
  • getAmat: automatic extract spatial adjacency matrix from the polygon file.
  • hatchPlot: plot variables on a map with hatching indicating the width of the credible interval.

+New methods * fitINLA2: implements new smoothing methods based on binomial models at cluster level.
