Anova in Knime


I am not able to run an Anova on my dataset, the config window is not giving me the string columns and giving the numeric columns only

please can you you help in telling me what am i doing wrong

Hi @ajverma19,

the ANOVA only works with numeric features, since it relies on statistical values like mean or deviation which are not well defined for strings. If your string columns represent numbers, I’d recommend the String to Number node to convert them first. If it is categorical data you are dealing with, you might try the category to number node - but I don’t know whether ANOVA would make a whole lot of sense for this kind of data.

Kind regards,
