For example, you could use multinomial logistic regression to understand which type of drink consumers prefer based on location in the UK and age i. Alternately, you could use multinomial logistic regression to understand whether factors such as employment duration within the firm, total employment duration, qualifications and gender affect a person's job position i.

However, before we introduce you to this procedure, you need to understand the different assumptions that your data must meet in order for a multinomial logistic regression to give you a valid result. We discuss these assumptions next. If you would like us to add a premium version of this guide, please contact us. When you choose to analyse your data using multinomial logistic regression, part of the process involves checking to make sure that the data you want to analyse can actually be analysed using multinomial logistic regression.

You need to do this because it is only appropriate to use multinomial logistic regression if your data "passes" six assumptions that are required for multinomial logistic regression to give you a valid result. In practice, checking for these six assumptions just adds a little bit more time to your analysis, requiring you to click a few more buttons in SPSS Statistics when performing your analysis, as well as think a little bit more about your data, but it is not a difficult task.

Before we introduce you to these six assumptions, do not be surprised if, when analysing your own data using SPSS Statistics, one or more of these assumptions is violated i. This is not uncommon when working with real-world data rather than textbook examples, which often only show you how to carry out a multinomial logistic regression when everything goes well!

Even when your data fails certain assumptions, there is often a solution to overcome this. First, let's take a look at these six assumptions:. Assumptions 1, 2 and 3 should be checked first, before moving onto assumptions 4, 5 and 6. Just remember that if you do not run the statistical tests on these assumptions correctly, the results you get when running a multinomial logistic regression might not be valid.

In the section, Procedure , we illustrate the SPSS Statistics procedure to perform a multinomial logistic regression assuming that no assumptions have been violated. First, we introduce the example that is used in this guide. A researcher wanted to understand whether the political party that a person votes for can be predicted from a belief in whether tax is too high and a person's income i.

Therefore, the political party the participants last voted for was recorded in the politics variable and had three options: "Conservatives", "Labour" and "Liberal Democrats". The researcher also asked participants their annual income which was recorded in the income variable. Note: For those readers that are not familiar with the British political system, we are taking a stereotypical approach to the three major political parties, whereby the Liberal Democrats and Labour are parties in favour of high taxes and the Conservatives are a party favouring lower taxes.

Note: In the SPSS Statistics procedures you are about to run, you need to separate the variables into covariates and factors. For these particular procedures, SPSS Statistics classifies continuous independent variables as covariates and nominal independent variables as factors. Therefore, the continuous independent variable, income , is considered a covariate.

However, where you have an ordinal independent variable, such as in our example i. In our example, it will be treated as a factor. The six steps below show you how to analyse your data using a multinomial logistic regression in SPSS Statistics when none of the six assumptions in the previous section, Assumptions , have been violated. At the end of these six steps, we show you how to interpret the results from your multinomial logistic regression.

Note: The default behaviour in SPSS Statistics is for the last category numerically to be selected as the reference category. In our example, this is those who voted "Labour" i. SPSS Statistics will generate quite a few tables of output for a multinomial logistic regression analysis. In this section, we show you some of the tables required to understand your results from the multinomial logistic regression procedure, assuming that no assumptions have been violated.

The Goodness-of-Fit table provides two measures that can be used to assess how well the model fits the data, as shown below:. The first row, labelled " Pearson ", presents the Pearson chi-square statistic. Large chi-square values found under the " Chi-Square " column indicate a poor fit for the model. A statistically significant result i. You can see from the table above that the p -value is.

Based on this measure, the model fits the data well. The other row of the table i. These two measures of goodness-of-fit might not always give the same result. Another option to get an overall measure of your model is to consider the statistics presented in the Model Fitting Information table, as shown below:. The " Final " row presents information on whether all the coefficients of the model are zero i.

Another way to consider this result is whether the variables you added statistically significantly improve the model compared to the intercept alone i. Variables in the EquationBS. Exp B Step 1agender1. Consider the Medical group a reference group.

Dummy variables are: Cosmetic, Theory, Meat, Veterin. Block 0 Look at Variables not in the Equation. Score is how much -2LL would drop if a single variable were added to the model with intercept only. Adding Purpose dropped -2LL to Classification TableYOU calculate the sensitivity, specificity, false positive rate, and false negative rate.

Wald Chi-SquareA conservative test of the unique contribution of each predictor. Presented in Variables in the Equation. Alternative: drop one predictor from the model, observe the increase in -2LL, test via 2. Odds Ratios Exp B Odds of approval more than cut in half. Odds of approval multiplied by 1. Odds of approval if purpose is Theory Testing are only. Odds of approval if purpose is Agricultural Research are only. Inverted Odds RatiosSome folks have problems with odds ratios less than 1.

Just invert the odds ratio. That is, respondents were more than two times more likely to approve the medical research than the research designed to feed the poor in the third world. Classification Decision RuleConsider a screening test for Cancer. Which is the more serious errorFalse Positive test says you have cancer, but you do notFalse Negative test says you do not have cancer but you doWant to reduce the False Negative rate?
