| Summary: | Nowadays people always read about criminal such as raping, killing, robbery and others
especially among people who are have relationship with offender. Murder or rape is
one of common criminal that people often heard in news because these numbers of
cases are increase every day. In order to solve the crime, forensic department and police
will cope together. Additionally, there is a lack of research about victims and offender
relationship when it comes to solving the crime and not all mathematical method can
give the absolute answer to calculate the perpetrators profiling. The objectives of this
research are to calculate the probability ofrelationship between victims and offender of
the murder cases using Logistic Regression Model and to the determined whether the
model is suitable to be used to analyze the data. In this research, there are two types of
logistic regression that are use which are binomial and multinomial. For the binomial,
there are two categories of dependent variable only and four categories of dependent
variables for multinomial regression. The result from shows that the R 2 the model is
less than 60 percent. Even though the R2 is not significant but there are a few tests that
are significant such as Omnibus and Wald test. Therefore, this method is still valid to
use to analyse the data set. For the recommendation data can be analyze by using other
model such as Association Rule Mining (ARM) because ARM is one of the models that
can show the relationship between data items and large data set in various type of
database. |
