WebIn order to create a standard curve we created 5 dilutions of solutions containing red dye #40. Concentrations of .666 ug/mL, 1.667ug/mL, 3.333ug/mL, 13.333ug/mL, and 20.000 were measured in a spectrophotometer set to a wavelength of 504 nm to find the amount of light they absorbed. Web17 aug. 2024 · Image provided by the author. The interpretation of the survival curve is quite simple, the y-axis represents the probability that the subject still has not experienced the event of interest after surviving up to time t, represented on the x-axis.Each drop in the survival function (approximated by the Kaplan-Meier estimator) is caused by the event …
Web9 feb. 2024 · To have a robust calibration line (or curve), a series of replicates of each standard (at least three replicates of 6–8 expected range of concentration values) are recommended. The assumption for this model is that the measurement error is the same and normally distributed for each sample.
