The statistical technique forecasts the relationship between
the dependent variable (Y) and the independent variable (X) when
the dependent variable is binary. The maximum likelihood (ML)
technique, which maximizes the probability of classifying the
observed data into the right
category given the regression
coefficients, is used to create the best-fitting function in
logistic regression. If the probability of success is estimated
(assuming Y is a dichotomous variable with values of 1) for the
occurrence of the event of interest (success) and 0 for thes
opposite case (failure), the logistic regression model is defined
by the equation:
P(Y = 1x1,x2, xk)
1 + eßo+Σ11 =x
k are logistic regression coefficients,
independent variables, which can be both measurable
Where ẞi i = 0,
X1, X2,
and qualitative.
The logit form of the logistic model could be obtained by
logarithmizing both sides of the equation:
P(Y = 1x)
logit P(Y = 1X) = In 1 - P(Y = 1x)
*
= Bo+ B1 X1
The logistic regression model has its own set of criteria.
Its application is constrained by the test sample size, which must
be more than or equal to n > 10 (k + 1), where k is the number of
predictors.
