TKDENSITY: Stata module for univariate kernel density estimation with calculation on transformed scale

Nicholas Cox

Statistical Software Components from Boston College Department of Economics

Abstract: tkdensity estimates and graphs kernel density estimates for the density function of a numeric variable, doing the calculations on a specified transformed scale and back-transforming to show density versus the original scale. It is a convenience wrapper for kdensity. Transformations implemented are natural logarithm, cube root, square root, reciprocal and logit.
