The ** operator will, internally, use an iterative function (same semantics as built-in pow () ( Python docs ), which likely means it just calls that function anyway). Therefore, if you know the power and can hardcode it, using 2*2*2 would likely be a little faster than 2**3. This has a little to do with the function, but I believe the main ...The %in% operator in R allows you to determine whether or not an element belongs to a vector or data frame.

In order to conduct an ANOVA, we need to need to perform three steps: 1) Generate a model that fits our design, 2) Fit our data to the model to obtain the parameter estimates, 3) Derive the statistics using a summary function of the model fit. In Python, these steps are implemented in the statsmodels library.It is possible to use masked arrays, but we don't do that in scikit-learn (yet). NaN in Pandas is numpy's nan value. for pandas take a look at this. pandas uses NaN. You can test for null values using isnull () or not null (), drop them from a data frame using dropna () etc. The equivalent for datetime objects is NaT.
