Error in t(partial) %*% vcov #7

Closed LHMarshall closed 1 year ago

LHMarshall commented 1 year ago

The following error was occuring sometimes:

# Fitting half-normal key function with Hermite(4,6) adjustments
# Warning: First partial hessian is singular; using second-partial hessian
# Warning: First partial hessian is singular; using second-partial hessian
# AIC= 932.07
# Error in array(x, c(length(x), 1L), if (!is.null(names(x))) list(names(x),  : 
#   'data' must be of a vector type, was 'NULL'
# Error in t(partial) %*% vcov : 
#   requires numeric/complex matrix/vector arguments

When calculation of the first partial hessian fails it looks to the second partial hessian... this either didn't work either or is NULL.
