Hi Rui, I was not aware of this function, however it looks like it should work for me. Many thanks for this intuition. However, in my optimization there are 3 constraints as below, 1) sum of all parameters should be 1 2) all parameters should be positive 3) last parameter should be greater than

I haven't run your code, but since Kendall correlation is based on ranks, your Fn is probably locally constant with jumps when the ranks change. That's a really hard kind of function to maximize, and the algorithm used by fmincon is not appropriate to do it. Sorry, but I don't know if there i

Perhaps read the Posting Guide, note that there is a special mailing list for MacOSX-specific questions, and post there instead? You don't appear to have installed gfortran. I am aware that there are specific instructions for getting that installed in MacOS that you need to find and follow [1].

Re: [R] Problem of intercept?

Not sure what you are trying to do here. The immediate issue is that you are getting 'y' on the RHS, because that is the 1st column in Dataset. So "for (i in 2:3)" might be closer to intention. However, a 0/1 regresson with no intercept implies that the mean for the "0" group is zero, and with

Re: [R] Problem of intercept?

Sigh... In a linear model with qualitative predictor variables, models with and without intercepts are just different parameterizations of the *same* model. -- they produce exactly the same predicted responses. So what do you mean? Search on "contrasts in linear models R" and similar for an expl

Maybe it is the order. You called py_install() first and then called use_condaenv(). Perhaps you need to switch to your conda env first and then call py_install(). On 01/20/23 16:20, Kai Yang via R-help wrote: Hi Team,I'm trying to run python in R markdown (flexdashboard). The code is below: t

`subdivisions` is the maximum number of subintervals. Looking here https://github.com/wch/r-source/blob/79298c499218846d14500255efd622b5021c10ec/src/appl/integrate.c#L1275 I'm not surprised that changing `subdivisions` has no effect on the outcome. The integration method from {pracma} might work,

You're dividing 0 by 0, giving you NaN, perhaps you should try function(x) ifelse(x == 0, 0, x^3/sin(x)) On Sat, Jan 7, 2023, 22:24 Leonard Mada via R-help wrote: > Dear List-Members, > > I encounter a problem while trying to integrate the following function: > > integrate(function(x) x^3 / sin
