Description Currently the von_mises_lpdf function can overflow for large values of kappa. Because of this, using it in stan usually requires a conditional statement to use a normal distribution approximation for kappa > 100. For example,...

Probability distribution functions (PDFs)describe the expected values of random variables drawn from a sample. The shape of the PDF explains how likely it is that an observed value might occur. Stock prices and returns tend to follow a log-normal distribution rather than a normal one, indicating...
