Time series fitting: use of 'trend' in VAR models via statsmodels.tsa.vector_ar.var_model.VAR

I'm using the statsmodels.tsa.vector_ar.var_model.VAR package to fit some bivariate time series. That is, time series of vectors with 2 components: (x1, y1)T, ..., (xN, yN)T. However, I do not understand how to use the parameter trend in the…

Fast way to find k nearest neighbors from only past, in R?

Assume I have a numeric data with 10,000 rows and 8 columns. I want to obtain the first k neighbors for each row (skipping first 1,000 rows) using euclidean distance but the catch is for each row I am only interested in the previous rows. (e.g. for…

How to use a multidimensional array (3D or 4D) for time series classification

I just can't wrap my head around this so I decided to ask. Imagine that you have a 3D array with 6 layers. Each of these layers contain data about 6 people demonstrating 6 different movements 10 times. Each movement varies in length, the longest…
