Logistic regression model

Suppose we decide to use the logarithm of the odds ratio as the link function. The logarithm of the odds ratio is called the logit. We set it equal to the linear function of 

The observation has the binomial(l, JTi) distribution. Each observation has its own probability of success. 

The logit is linked to the linear predictor, an unknown linear function of the predictor variables. 

When we solve this equation for tt, we get the logistic equation 

This joint likelihood cannot be factored into the product of the individual likelihoods

Figure 3. The logistic regression model used to estimate LD50 is represented on the left where 7C represents the proportion of dead plants. The logistic curve can be linearized by using the logit transformation shown on the right. LD50 values were estimated with the regression coefficients for logit 7C=0.0, as shown in the inset box.

Logistic regression modeling is used for predicting the probability of occurrence of an event by fitting data to a logistic curve.28 It describes the relationship between the categorical response variable and one or more continuous variables.29 Such a model can be described in Equation 3 ...
