1.1 | 07/13/2016 | Increases the maximum number of blocks that can be included in the analysis for BLOCK_FE=1 designs. For blocked designs, RCT-YES automatically invokes the super-population model (SUPER_POP=1) if the model contains too many blocks. This design feature was implemented to minimize the chances that the R or Stata programs will crash because of too many model covariates. In Program Version 1.0, for finite-population specifications, the super-population is invoked if (2bs + x) > 200, where b is the number of blocks, s is the number of subgroup levels for a subgroup analysis (and 1 for the full sample analysis), and x is the number of baseline covariates. This same rule is used for the default BLOCK_FE=0 specification and for the optional BLOCK_FE = 1 specification where the model includes block indicators but not block-by-treatment interaction terms. In Version 1.1, the rule for invoking the super-population model for the BLOCK_FE=1 specification is now (bs+s+ x) > 200 instead of (2bs + x) > 200, reflecting the smaller number of model covariates for this specification. | ✔Applies to R | ✔Applies to STATA | Does not apply to RCT-YES-Graph | Does not apply to RCT-YES interface |

1.1 | 07/13/2016 | Fixes bugs that caused the program to crash for numeric subgroup variables when the user specifies both numeric and non-numeric codes in the interface. Users may inadvertently specify both numeric and character codes for a particular subgroup variable (for example, a code of 0 for males and F for females for the numeric subgroup variable GENDER). The program can now handle these input errors and will exclude the subgroup from the analysis in these instances. | ✔Applies to R | Does not apply to STATA | Does not apply to RCT-YES-Graph | Does not apply to RCT-YES interface |

1.1 | 07/13/2016 | Fixes bugs that caused the program to crash for some cases where the same variable is specified more than once in the interface. The program can now handle instances where the same variable is specified as an outcome, covariate, weight, and/or subgroup. Although some of these combinations will be highly unusual (for example, specifying an outcome variable as a weight variable), the program allows them. | ✔Applies to R | ✔Applies to STATA | Does not apply to RCT-YES-Graph | Does not apply to RCT-YES interface |

1.1 | 07/13/2016 | Fixes all potential scalar/variable conflicts. In Stata, there are scalar variables and data variables. Scalar variables are similar to macro variables and are used throughout the Stata RCT-YES program to store numeric constants. Recent testing revealed the potential for overlap between these two types of variables, where the data variable would be used instead of the scalar variable. The code was modified to add the scalar() function to all scalar variable references to avoid any scalar/data variable naming collisions. | Does not apply to R | ✔Applies to STATA | Does not apply to RCT-YES-Graph | Does not apply to RCT-YES interface |

1.1 | 07/13/2016 | Improves error messages for some subgroup analyses in Table 1 of the .html file. Table 1 now lists the outcome variable associated with certain subgroup exclusion error messages so that these errors can be more easily identified and fixed. | ✔Applies to R | Does not apply to STATA | Does not apply to RCT-YES-Graph | Does not apply to RCT-YES interface |

1.1 | 07/13/2016 | Prints footnotes for the "Treatment-control means" chart for the "Line graph" option in RCT-YES-Graph. These footnotes describe the symbols used in the graph to signify statistical significance of the impact estimates. | Does not apply to R | Does not apply to STATA | ✔Applies to RCT-YES-Graph | Does not apply to RCT-YES interface |

1.1 | 07/13/2016 | Adds a blank line between the graph title and the graph in RCT-YES-Graph. The spacing of the title is now parallel to the spacing of the footnotes. | Does not apply to R | Does not apply to STATA | ✔Applies to RCT-YES-Graph | Does not apply to RCT-YES interface |

1.1 | 07/13/2016 | Fixes bug to allow RCT-YES to be launched by opening a previously-saved input specification (.rctyes) file from the directory where it was saved. Previously, clicking on the .rctyes file would not launch the interface if there was a space in the .rctyes file’s path name. This problem is now resolved. | Does not apply to R | Does not apply to STATA | Does not apply to RCT-YES-Graph | ✔Applies to RCT-YES interface |
