mdsstat 0.3.3

UNDER DEVELOPMENT

Potential Updates

• Allow eval_period parameter in algorithms to be max number of df rows, thus full contingency table analysis. Will need to account for un-runnable sequential analysis.

mdsstat 0.3.2

Implemented Updates - Moved Poisson MaxSPRT algorithm to development branch maxsprt on Github - Explicit declarations of stringsAsFactors=T in all data.frame() calls for cross-version compatibility

mdsstat 0.3.1

Implemented Updates

• Added LRT algorithm
• Added Poisson MaxSPRT algorithm

mdsstat 0.3.0

Implemented Updates

• Added EWMA algorithm
• Added mean-shift changepoint algorithm
• Carry over time series ID for mds_ts objects to run_algos() output.
• Deprecated shewhart() function name. Replaced with xbar() for clarity.
• Added options in shewhart()/xbar(), cusum(), and ewma() to explicitly declare mu and sigma

Bugfixes

• Various documentation errata

mdsstat 0.2.2

Implemented Updates

• Added SPRT algorithm
• Added GPS algorithm
• Added BCPNN algorithm

Bigfixes

• Fixed analysis_of attribute for all algorithms

mdsstat 0.2.1

Implemented Updates

• Added continuity adjustment option to DPA algorithms prr() and ror()
• Added CUSUM algorithm
• Added ROR algorithm
• Added support for more complete hierarchical descriptions (see mds package)
• Reorganized R scripts for easier navigation

Bugfixes

• shewhart() mu and sigma no longer calculated using the current index month

mdsstat 0.2.0

Implemented Updates

• run_algos(): add parameter to skip/warn/stop when trying to run DPA on non-DPA time series
• Allow run_algos() to run on a list of mds_ts or other properly formatted objects

Bugfixes

• shewhart() now outputs the correct signal logic
• prr() now outputs the correct signal logic and p-value

mdsstat 0.1.0

• Initial Release. Yay!
