Automatic differentiation in R with Stan Math | R-bloggers .grad[, "A"] .grad[, "lam"] .grad[, "b"] attr(.value, "gradient") .value #> } Since we specified the function.arg argument, deriv() returns a function –instead of an expression– that can be used directly to evaluate both the function values and the gradient (or Jacobian) for different values of the independent variable and parameters. Inspecting the body of the returned function, we see that the expression in the "gradient" attribute corresponds exactly to the manually derived gradient. ## evaluate function + jacobian fdot(x = (1:10) / 10, ...

If you are interested in other posts of this series, please go to: https://www.statforbiology.com/tags/drcte/ In the previous post we have shown that time-to-event curves (e.g., germination or emergence curves) can be used to describe the time course of germinations/emergences for a seed lot (this post). We have also seen that the effects of experimental factors on seed germination can be accounted for by coding a different time-to-event curve for each factor level (this post). In this post, we would like to consider the ... Read More

Feed: R-bloggers. Author: Avi. This post outlines the steps needed for building R 4.2 for Windows with OpenBLAS using the the new Rtools42 build system. With the soon-to-be released new UCRT toolchain for building R on Windows, the build process changes once again. First and foremost, we Windows users owe a deep debt of gratitude first to Duncan Murdoch who supported the Windows builds through R3, then Jeroen Oomes who updated and re-platformed the toolchain for R4, and now Tomas Kalibera who has updated the toolchain to comply with R-core’s requirement that the default build for windows be UCRT-compliant and ...
