What is your perception on using visual analysis or quantitative approaches to evaluate data from single-case research designs (n of 1 trials)?

Results of single-case research designs (i.e., n-of-1 trials) are often evaluated by visually inspecting the time-series graph and computing quantitative indices. A question our research team is...

I am not sure if I understand you correctly, but have you set the number of time units to forecast (default value is "1")?

HTH.

Dr. Samer Sarsam

Yes, the number of time units to 1 was set. I am not sure that dataset shift may play a role in this case. I am quite new in neuron network. I observed this feature in the linear regression, multilayer perceptron, and SMOreg. I show a result for example as attached file below.

You need to change the value 1 into the number of units that you tend to examine. The result obtained from the test set is the one needs to be considered when evaluating the model; hence, make sure it shows low RMSE values.

Cheers,
