Time-series analysis calculator with steps. Solve the forecast error, mean absolute error, mean squared error and more.
5 paź 2023 · Similarity between time series can be determined by using distance measures to measure its inverse: dissimilarity. Dissimilarity is more intuitive as a measurement because a value of zero occurs when two time series are identical (while similarity has a scale-dependent maximum value).
Time series line graphs are the best way to visualize data that changes over time. This is because line graphs show how a variable changes from one point in time to another, making it easy to see trends and patterns.
28 maj 2016 · In this paper, the TSdist package is presented, a complete tool which provides a unified framework to calculate the largest variety of time series dissimilarity measures available in R at the moment, to the best of our knowledge.
Computes the distance measure based on the cross-correlation between a pair of numeric time series. Usage CCorDistance(x, y, lag.max=(min(length(x), length(y))-1))
In the next level, the wrapper function called TSDistances enables the calculation of distance measures between univariate time series objects of type ts, zoo and xts, the latter two defined in their respective packages: zoo (Zeileis and Grothendieck, 2005) and xts (Ryan and Ulrich, 2013).
10 lip 2017 · Given a quite noisy reference time-series $A$ (about 10k observations), and a bunch of equally sampled time-series $K^i$, is it possible to classify the $K^i$ according to their proximity to $A$? In other words I would like to define a distance measure to the reference time-series.
