independent variable with errors made when making predictions that use information about the independent variable. E1 = errors of prediction made when the independent variable is ignored E2 = errors of prediction made when the prediction proportional reduction in error stata is based on the independent variable "All PRE measures are based on comparing predictive error levels that result from each of two methods of prediction" (Frankfort-Nachmias and Leon-Guerrero 2011:366). Table 12.1 on page 366 of the textbook helps us to understand this. The independent variable is number of children; the dependent variable is support for abortion.

Two PRE Measures: Lambda and Gamma Lambda λ Appropriate for: Nominal Variables Gamma γ Appropriate for: Ordinal and Dichotomous Nominal Variables

What’s the best way to do that? having a mental medical reduction in error condition financial status   relatively bad relatively good total yes 390 (97,5 %) 10 (2,5 %) 400 (100 %) no 40 (6,7 %) 560 (93,3 %) 600 (100 %) total 430 (43 %) 570 (57 %) 1000 (100 %) Declareing each respondent to have a relatively good financial status is the safest way: thus we are wrong in 430 cases out of 1000.How does the situation change if we already know Table 1 and we can ask each respondent whether or not they have a mental medical condition?In this case we can improve the chances of our guesswork by categorizing everyone with a mental problem as having worse financial status, while those without mental problems as having better financial status. Thus the number of mistakes we make is down to 50.In other words, the guessing error characterizes the relationship of the two variables. Associational indices that work on this principle are called ’proportional reduction of error’ (PRE) indices.Calculating (λ) to get the connection of two nominal variables:8.1. egyenlet - Where:E1 is

Nominal Measures of Association Ordinal Measures of Association Introducing Control Variables Interpreting Control Tables Contingency Tables After examining the univariate frequency distribution of the values of each variable separately, the researcher is often interested in the joint occurrence and distribution of the values of the independent and dependent variable together. The joint distribution of two variables is called a bivariate distribution. A contingency table shows the frequency distribution of the values of the dependent variable, given the occurrence of the values of the independent variable. Both variables must be grouped into a finite number of categories (usually no more than 2 or 3 categories) such as low, medium, or high; positive, neutral, or negative; male or female; etc. Constructing a Contingency Table 1) obtain a frequency distribution for the values of the independent variable; if the variable is not divided into categories, decide on how to group the data. 2) obtain a frequency distribution for the values of the dependent variable; if the variable is not divided into categories, decide on how to group the data. 3) obtain the frequency distribution of the values of the dependent variable, given the values of the independent variable (either by tabulating the raw data, or from a computer program) 4) display the results of step 3 in a table Example: Independent Variable: Place of Residence Categories: Inside City Limits=505 Outside City Limits=145 Dependent Variable: Attitude about Consolidation Categories: Favor consolidation=327 No Opinion=168 Against consolidation=155 Joint Distribution: Table 1.
