Total Scores and data #458

Closed pukelevicius closed 3 years ago

pukelevicius commented 3 years ago

Good day! I am exploring ShinyItemAnalysis package with quite large test dataset, which consists of ordinal 40 items (questions) and 15k rows (participants). First, I would like to know why in summary->standard scores the total score value is 20 max, because I know in my data participants can score more than 20 points. The second issue is with Traditional item analysis table which outputs me an error: "incompatible dimensions", how can I solve it? In general, I am interested in obtaining z_scores for each participant and question metrics, however I do not have luxury of obtaining group data and DIF matching variable vector. Thanks, Domantas

Hello, which version of ShinyItemAnalysis are you using? Please try the newest GitHub version 1.3.5-1. Some issues with data loading appeared in version 1.3.5 and are now solved with the 1.3.5.-1 version. No worries about group or DIF matching vector if you do not have them, those are not needed for the analyses you mentioned you are interested in. Best, Patricia
