WebStep 2 - Define a factor. After defining a universe, the next step is to define a factor for testing. On Quantopian, a factor is a computation that produces numerical values at a regular frequency for all assets in a universe. Similar to step 1, we will use the the Pipeline API to define factors. WebComputing the Pearson correlation coefficientbetween variables Xand Yresults in approximately 0.970, while computing the partial correlation between Xand Y, using the formula given above, gives a partial correlation of 0.919. The computations were done using Rwith the following code.

Durbin Watson Statistic - Overview, How to Calculate and Interpret

Autocorrelation, sometimes known as serial correlation in the discrete time case, is the correlation of a signal with a delayed copy of itself as a function of delay. Informally, it is the similarity between observations of a random variable as a function of the time lag between them.
