The logistic regression method assumes that: The outcome is a binary or dichotomous variable like yes vs no, positive vs negative, 1 vs 0. There is a linear relationship between the logit of the outcome and each predictor variables. Recall that the logit function is logit (p) = log (p/ (1-p)), where p is …
NettetLogistic regression analysis can also be carried out in SPSS® using the NOMREG procedure. We suggest a forward stepwise selection procedure.

NettetThe linearity of the detector response to the test pesticide was demonstrated by a single injection of the calibration standards in solvent (acetonitrile) at eight concentration levels ranging from 0.0003 μg/mL to 0.04 μg/mL, which corresponds to 0.003 mg/kg to 0.4 mg/kg. A weighted curve (1/x) was used.
