Hi,

In case, target variable has no data present, which technique should be used for prediction and how can we check the accuracy of model afterwards

It would depend on what your goal is! Are you running statistical analysis? Are you trying to build predictive model?

Usually, in case you don’t have target variables and you want to group your data in some classes based on some variables, you need to think of unsupervised learning methods.
