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 guess it would be helpful if you could share with us some more information about the system you are studying. In any way, in my experience the results of FDTD simulations are only as good as the dielectric functions you use. E.g. the optical constants of gold in the middle infrared vary depending on the source drastically and so do the plasmon absorptions of corresponding structures concerning frequency and intensity...

Kaleem Ullah

actually i am trying to get the near field scattering spectra around a metal alloy by using a new numerical method,for that method I have a system which is called polarization indirect microscopy. i have experimental results from that system which are in terms of polarization parameters like stokes parameters ,polarization angle etc. same i have performed in calculations but i have got more field variations in results of near field as compared to the experimental.
