Macros SAS DocumentsDate added
It is a macro which allows to rapidly validate a pronostic model
thanks to discirmination (AUC and ROC curve), calibration
(Hosmer-Lemeshow test and graph) and summarize quality of the model at
the end.
You just must have probability of outcome and the outcome in a table.
This macro is very interesting for a validation dataset of a logistic model.

It is a macro which allows to find risk factor of outcome for qualitative variables.
You can test binary or classes variables. A Khi2 test for each modality is available.
Results are presented with frequencies, percentages, Khi2 test and missing values.
An example will help you

It is a macro which allows to transform quantitative variables in classes.
You
can choose the number of classes (2,4,5,10...)and the type of
transformation : several binary variables according the percentile or
only one new variable divided in 'n' classes.
An example will help you.

It is a macro which allows to transform qualitative variables in binary variables.

It is a macro which allows to find imbalances between groups for quantitative variables according to an outcome binary variable.
You
have just to put the list of variables to test and you can choose the
appearance of results (complete or simplified presentation).
An example will help you.

Macro to describe quantitatives variables in a cohort (median, mean, quartiles... and missing values)

Macro to describe cohort with only frequencies, percentages and missing values for each modality of qualitative variables

It is a macro which allows to deconcatenate variable which contain multiple values separated by a character.
For
example, if a variable is '674|675|676|677', we then create 4 new variables
: 674 for the first, 675 for the second...until the last.
An example will help you.
Adrien FRANCAIS and Valérie SIROUX
It is a macro which allows to decompose variables created in additional
codes. We then obtain several variables with unique code to clearly
identify value.
For example, if a variable is 19, we create 3 new variables with the
code 16 for the first, 2 for the second and 1 for the last.
An example will help you.

Macro to compare two groups according to a binary variable.
Effectives and Frequencies are computed for qualitative variables.
Distribution is described for quantitative variables.
Differences between groups is computed thanks to Khi2 test and Kruskall-Wallis test.
If
the analyse is stratified, a term is available for that and pvalue
appropriate is computed in logistic conditional regression.

It is a macro which allows to select automatically fixed effects in PROC GLIMMIX.
You
can choose the type of selection (BACKWARD or FORWARD), the threshold,
until 5 level of random effects and force a variable in the model.
In order to algorithm converge, datafile must have not a lot of missing values
