- Sometimes even the linear techniques are too rich, such as when the variables are sampled versions of a smooth function or image. The exponential growth in computer processing speed and storage has allowed us to routinely gather data where each observation is one or more digitized image. This has lead to a new field currently known as functional data analysis, and is filled with many interesting (open) problems, because the traditional techniques no longer work.
