impure subroutine s_tst_anova_1w(x, f, df_b, df_w, p)

! ==== Description
!! Impure wrapper procedure for `s_tst_anova_1w_core`.

! ==== Declarations
  real(wp), intent(in)  :: x(:,:) !! 2D array, each column is a group
  real(wp), intent(out) :: f      !! F-statistic
  real(wp), intent(out) :: p      !! p-value from F distribution
  real(wp), intent(out) :: df_b   !! degrees of freedom between groups
  real(wp), intent(out) :: df_w   !! degrees of freedom within groups

! ==== Instructions

! ---- handle input

  ! check that no. of elements and groups (must both be 2 or higher)
  if (size(x, 1) .le. 1 .or. size(x, 2) .le. 1) then
     ! write error message and assign NaN value if invalid
     call s_err_print(fsml_error(4))
     f    = f_utl_assign_nan()
     p    = f_utl_assign_nan()
     df_b = f_utl_assign_nan()
     df_w = f_utl_assign_nan()
     return
  endif

! ---- conduct test

  ! call pure procedure
  call s_tst_anova_1w_core(x, f, df_b, df_w, p)
