title: Time-series vs sequence terminology
body: <p>I'm developing a C++ class library for time-series modeling. I've run into some naming/terminology issues.  I am unsure whether I should name one of my template collection classes 'class series&lt;>' or 'class sequence&lt;>'. </p>
  
  <p>Mathematically speaking a 'series' is the sum of a 'sequence', but when we speak of a 'time series' there is no sum involved!? I am wondering which part of the 'time series' is actually the 'series' (if any).</p>
  
  <p>More specifically, imagine two columns in a table. One holds the time_points and the second the corresponding values. The C++ class I need to name holds the data from either of these columns. The class is however not used in the context of a 'table' but rather a 'model' or 'strategy'. </p>
  
  <p>My question is: Am I technically wrong naming the class 'series'? Should it be named 'sequence' instead? </p>
