Description

Enables Blind Review of Database.

Randomly reassigns the group identifications to one of the variables of the database, say Treatment, and randomly reassigns the observation numbers of the dataset. Reorders the observations according to these new numbers. Centers each group of Treatment at the grand mean in order to further mask the treatment. An unmasking function is provided so that the user can identify the potential outliers in terms of their original values when blinding is no longer needed. It is suggested that a forward search procedure be performed on the masked data. Details of some forward search functions may be found in <https://CRAN.R-project.org/package=forsearch>.

blindreview

The goal of blindreview is to transform a database by masking the identity of the treatments and of the observation numbers so that the data may be reviewed in the absence of treatment knowledge. This database is suitable for a forward search using the forsearch package. The outcome of that package is a set of graphs that identify the best fitting observations and the worst fitting observations to the planned analysis of the data without also identifying the treatment that resulted in these observations. With regard to clinical trials, the US Food & Drug Administration guidance for industry "E9 Statistical Principles for Clinical Trals" is an important reference.
