No changes to the code are necessary: • Projected and achieved growth values are already computed using inoc.log.OD • Lag is computed directly from Zwietering's formulas. It is displayed correctly on plots, too. According to Zwietering, "The lag time is defined as the t-axis intercept of the tangent through the inflection point": see equations 7 and 8. Therefore, in GCAT, it is correct to display lag as the intersection between the tangent and the baseline.
Need to make sure that (estimated) inoculation OD, or its natural log, is consistently used as the baseline value, not parameter b of sigmoid equations.
