model_is_stable(varest)

Arguments

varest

A varest model.

Value

This function returns TRUE if the model satisfies the Eigenvalue stability condition and FALSE otherwise.

Examples

# NOT RUN {
data_matrix <- matrix(nrow = 40, ncol = 3)
data_matrix[, ] <- runif(ncol(data_matrix) * nrow(data_matrix), 1, nrow(data_matrix))
colnames(data_matrix) <- c('rumination', 'happiness', 'activity')
varest <- autovarCore:::run_var(data_matrix, NULL, 1)
autovarCore:::model_is_stable(varest)
# }
