Windows 11
Bug Description
When calculating Coeffcient alpha (item dropped) I get a cryptic error message:
Error in A1 %*% M2: requires numeric/complex matrix/vector arguments
Stack trace
tryCatchOne(expr, names, parentenv, handlers[[1]])
doTryCatch(return(expr), name, parentenv, handler)
withCallingHandlers(expr = analysis(jaspResults = jaspResults, dataset = dataset, options = options), error = .addStackTrace)
analysis(jaspResults = jaspResults, dataset = dataset, options = options)
.frequentistComputeItemResults(jaspResults, dataset, options, model)
.seLambda3(dtUse[, -i])
.seLambda1(X, VC)
.varCM(X)
I think this is due to the treatment of missing values. If I set the treatment of missing value to listwise deletion (instead of pairwise) the analysis works.
Expected Behaviour
I would not expect a bug at all.
Steps to Reproduce
See my JASP file attached
