gIntAUC function

Calculate interval AUC of general form

Calculate interval AUC of general form

It calculates interval AUC of general form. This is useful for pharmacodynamic data.

gIntAUC(x, y, t1, t2, Outer = "NEAREST")

Arguments

  • x: vector values of independent variable, usually time
  • y: vector values of dependent variable, usually concentration
  • t1: start time for AUC
  • t2: end time for AUC
  • Outer: indicates how to do the out of x range point

Details

This calculates an interval (partial) AUC (from t1 to t2) with the given series of x and y. If t1 and/or t2 cannot be found within x vector, it interpolates. If t1 and/or t2 are out of x range, it uses the nearest value. For concentration data, use IntAUC.

Returns

return interval AUC value (scalar)
