Utility functions for input validity.

Utility function that checks if a given matrix is a valid delay distribution matrix. For this, the matrix needs to fulfill the following conditions:

  • is a numeric matrix

  • has no values < 0

  • is a lower triangular matrix

  • no column sums up to more than 1

  • no NA values

  • the size of the matrix is greater than the length of the incidence data

.check_is_delay_distribution_matrix(
  delay_matrix,
  incidence_data_length,
  parameter_name
)

Arguments

delay_matrix

A matrix to be tested
incidence_data_length

A number representing the length of the given incidence data.
parameter_name

A string containing the name the tested parameter had in the initial function in which it was passed.

Value

TRUE if all tests were passed. Throws an error otherwise.
