WebJun 1, 2024 · Comparative examples between ksdensity (row 1), kde (row 2), and PDFE (row 3) demonstrating multi-resolution scales for a tri-modal distribution. Column 3 shows … WebSep 29, 2024 · The ksdensity uses a nonparametric representation to calculate the probabilities, so there's no parameters to get from the function self. If, however, you know which distribution may be underlying it (or can make a good visual estimation), you can do a later parametric optimization of your data to get the parameters.

WebJan 3, 2024 · This option is only valid for bivariate sample data. For univariate data, if 'Support' is 'positive', then ksdensity transforms x using a log function, estimates the density of the transformed values, and transforms back to the original scale. If 'Support' is a vector [L U], then ksdensity uses the transformation log((X-L)/(U-X)). WebAsking for help, clarification, or responding to other answers.
