Error in gcc to compile packages in MacOSX

In MacOSX, if you have homebrew installed:

To prevent an error during compilation of packages, modify these two files:

sudo vi /Library/Frameworks/R.framework/Versions/Current/Resources/etc/Makeconf

In "Makeconf" change the line beginning by: FLIBS = 

by:

FLIBS =  -L/opt/homebrew/Cellar/gcc/14.2.0/lib/gcc/current/gcc/aarch64-apple-darwin23/14 -L/opt/homebrew/Cellar/gcc/14.2.0/lib/gcc/current -lgfortran -lquadmath -lm

and the one beginning by: FC =
by
FC = /opt/homebrew/bin/gfortran -arch arm64

Create a file 
sudo vi ~/.R/Makevars

with 

FC = /opt/homebrew/Cellar/gcc/14.2.0/bin/gfortran
F77 = /opt/homebrew/Cellar/gcc/14.2.0/bin/gfortran
FLIBS = -L/opt/homebrew/Cellar/gcc/14.2.0/lib/gcc/current

The value 14.2.0 must be changed depending on the current version.

I try this but it didn't work:

FC = $(find /opt/homebrew/Cellar/gcc/* -maxdepth 0 -type d)"/bin/gfortran"
F77 = $(find /opt/homebrew/Cellar/gcc/* -maxdepth 0 -type d)"/bin/gfortran"
FLIBS = -L$(find /opt/homebrew/Cellar/gcc/* -maxdepth 0 -type d)"/lib/gcc/current"

Standard error from Hessian Matrix... what can be done when problem occurs

An Hessian matrix is a square matrix of partial second order derivative. From the square-root of the inverse of the diagonal, it is possible to estimate the standard error of parameters. Let take an example: val=rnorm(100, mean=20, sd=5) # Return -ln L of values in val in Gaussian distribution with mean and sd in par fitnorm<-function(par, val) {   -sum(dnorm(val, par["mean"], par["sd"], log = TRUE)) } # Initial values for search p<-c(mean=20, sd=5) # fit the model result <- optim(par=p, fn=fitnorm, val=val, method="BFGS", hessian=TRUE) # Inverse the hessian matrix to get SE for each parameters mathessian <- result$hessian inversemathessian <- solve(mathessian) res <- sqrt(diag(inversemathessian)) # results data.frame(Mean=result$par, SE=res)   library(MASS) (r<-fitdistr(val, "normal")) It works well. However, the inverse of the matrix cannot be calculated if the second order derivative for some paramete...

stepAIC from package MASS with AICc

Due to a bug in dropterm() and addterm() in package MASS, it is impossible to use AICc with stepAIC() . Here is a solution. Enter these commands and now you can use: stepAIC(g0, criteria="AICc") or stepAIC(g0, criteria="BIC") For example: datax <- data.frame(y=rnorm(100), x1=rnorm(100),                     x2=rnorm(100), x3=rnorm(100), x4=rnorm(100)) g0 <- glm(y ~ x1+x2+x3+x4, data=datax) gx_AICc <- stepAIC(g0, criteria="AICc") gx_AIC <- stepAIC(g0, criteria="AIC") gx_AIC <- stepAIC(g0, criteria="BIC")
