| dc.description.abstract | ABSTRACT
Stands for Narcotics Drugs, Psychotropic Substances, Materials addictive, which is
the name of a class of natural substances, synthetic or semi synthetic. Factors that are
considered influential to the increasing abuse of drugs such as negative parent, make
friends with peers, as well as increased economic pressures of the evidence.
Formulation of the problem in a study titled "Backward Method for Determining the
Use of Multiple Linear Regression Equations (Khasus Study: Number of Drug Abuse
in Medan Police)" This is to determine the appropriate equation to estimate the
amount of drug abuse in the resort city of Medan police. To obtain the regression
equation using the method the author is Backward backward method which is a step
backwards, in which all the variables Xi regressed with the dependent variable Y.
pengeleminasian variable Xi Fpar based on the value of each variable Xi is a variable
that has the smallest value Fpar tangkah principal and co-absence of these variables in
the model is based on Ftab. Estimators obtained is: y = 1317 + X3 + X4 0293. With
the Y represents the number of drug abuse, X3 is the economic pressure, and X4 is
barangbukti and the percentage of variation (correlation coefficient of determination)
is described by the probe is at 55.1% so that we can conclude that the models are quite
good estimator is used as an estimate of the number of Police crime in Medan resort. | en_US |
