How to do a "Box's M" Test with
Trying to get past a frustrating error to do a "simple" Box's M test using Java. The Box's M test says it will work with a data.frame. Here's the setup code: REXP myDf = REXP.createDataFrame(new RList( new REXP[] { new REXPDouble(d1), new REXPDouble(d2), new REXPDouble(d3), new REXPDouble(d4), new REXPInteger(d5) })); Here's the call: REXP boxMResult = rConnection.eval( "boxM(" + myDf+ "[,-5], " + myDf + " [, 5])"); But, I keep getting syntax error...

Logistic regression
I have a data set to be analyzed using to binary logistic regression. The data set is iin grouped form. My question is: how I can compute Hosmer-Lemeshow test and measures like sensitivity and specificity? Any suggestion will be greatly appreciated. Thank you Endy [[alternative HTML version deleted]]

Trying to create R dataframe with JRI
...t and create REXP dataframes from those lists. I found an example here: http://code.google.com/p/jamsim/source/browse/trunk/JAMSIM/src/org/jamsim/r/RInterfaceHL.java?spec=svn52&r=52 ... RList rlist = new RList(vectors.size(), true); ... // turn the rlist into a dataframe REXP dataframe = REXP.createDataFrame(rlist); .... both of these constructors do not exist in JRI (apparently). They must use a different set of libraries (?) and I am now puzzeled. How can I create a dataframe from Strings and integers? I managed to create RVectors: ArrayList<RVector> vectors = new ArrayList<RVector>()...

How to create a table structure in Java code?
Thanks! I just figured it out (thanks to "Beyond Compare") and was coming here to post back. The boxM test doesn't work with that (now, finally working) REXP structure, but I probably now need to create a table or something and parse that structure. So much fun! :) Thanks again. - M Sent from [ProtonMail](https://protonmail.com), Swiss-based encrypted email. > --------
