Use thepredictLifetimefunction to get lifetime PDs on the training or the test data. To get conditional PDs, use thepredictfunction. For model validation, use themodelDiscriminationandmodelCalibrationfunctions on the training or test data.
At last, it's time for some visualizations! First, let's make a histogram to visualize the frequency distribution of all 3,577 words (i.e. the distribution of word_counts.values()). Details: We recommend using Matplotlib for this, since it allows you to customize the figure size. A fi...
Before we move to looking at the relationship between wins and population, it's useful to understand the distribution of wins alone. A few notes of interpretation: The number of wins is skewed and looks like a negative binomial distribution, which makes sense conceptually The "typical" value he...
EMD decomposes a time series into a non-oscillatory trend and a sequence of oscillatory intrinsic mode functions (IMFs) that differ in their characteristic frequencies. It allows for both nonlinearity and nonstationarity and gives an intuitive and data-driven understanding of the underlying fluctuations...
