# Logistic regression

To explore the association between multiple predictors and a dichotomous dependent variable, logistic regression analysis can be used. In this example, a dataset/dataframe called `dat`

contains two continuous variables, `independentVariable`

and `secondIndependentVariable`

, and one dichotomous dependent variable `dichotomousVariable`

.

## SPSS

```
LOGISTIC REGRESSION VARIABLES dichotomousVariable
/METHOD=ENTER independentVariable + secondIndependentVariable.
```

## R

```
logRegr(dichotomousVariable ~ independentVariable + secondIndependentVariable,
data = dat);
```

To also show a plot, use:

```
logRegr(dichotomousVariable ~ independentVariable + secondIndependentVariable,
data = dat,
plot = TRUE);
```
