The spiral of Archimedes has polar equation $r=a \theta$, where $r^2=x^2+y^2$. For example, you can use the model to predict all samples from prdata by removing .head () which restricts the DataFrame to the first 5 rows (but you just used this data to train the model; it's just an example). More accurate predictions are associated with, Correlations having higher absolute values. In this context, independent indicates that they stand alone and other variables in the model do not influence them.
