Helper function to check a data.table for two of mx, ax, and qx and compute the missing parameter if one is missing.

Usage

check_mx_ax_qx(dt)

Arguments

dt	[data.table()] Data to check for mx, ax, and/or qx. Must also have 'age_length' column.

  age_start = c(0, 1, 5, 10),
  age_length = c(1, 4, 5, 5),
  mx = c(0.009, 0.0004, 0.00015, 0.00019),
