Hi, I am trying to fit the inverse-Gaussian distribution to my failure data. I wrote a function to define the inverse-Gaussian distribution and tried to get posterior samples. I have no experience in defining new distributions in RStan. My codes produced the following error. SYNTAX ERROR, MESSAGE(…

It looks like the function is defined with a vector as input data (“vector x”), but you’re passing it an array of reals. You could either change the function code, or change your data statement from “real y[J]” to “vector[J] y”.
