v0.5.1

Added

• Count splitting:

  • output_type = 'rate' satisfies the condition that the population weighted mean of the post-split result adds up to the pre-split value.
  • output_type = 'total' satisfies the condition that the SUM of the post-split results adds up to the pre-split value.

• Age splitting columns:

  • Population_total: the sum of age group specific populations across a study.
  • Population_proportion: the normalized population in each post-split group.
  • Implication: can multiply population_proportion by sample study size to get the post-split pseudo sample sizes.

Fixed

• Error messaging in sex splitting if a population is missing.
• Error where pattern and pattern_sd were missing, but actually provided
