Do you measure or change the dependent variable?
The independent variable is the variable the experimenter manipulates or changes, and is assumed to have a direct effect on the dependent variable. The dependent variable is the variable being tested and measured in an experiment, and is ‘dependent’ on the independent variable.
What kind of variable is income?
ordinal
For example, income is a variable that can be recorded on an ordinal or a ratio scale: At an ordinal level, you could create 5 income groupings and code the incomes that fall within them from 1–5. At a ratio level, you would record exact numbers for income.
Can a count variable be treated as continuous?
Treating that count variable as continuous would give you predicted values that are non-integers, but perhaps that’s not a big issue in your particular data set. Q: How high does the count scale have to be before you can consider it continuous?
Can a continuous variable be used as an independent variable?
It sounds like your independent variable is actually a categorical variable with two levels. Continuous variables don’t have levels like that. You can perform simple regression with one categorical independent variable. However, for simplicity, you can perform a 2-sample t-test and assess the mean difference between your two groups.
When can count data be considered continuous SAS?
Hi Karen aim trying to analyse my data using SAS (GENMOD) all independent variables are categorical with different levels, while the 2 dependent variables are continous (Levels of aflatoxins and fumonisins in Maize samples). Can you please advice if Genmode is appropriate and how I can transform the data to fit linear model.
Can a binary dependent variable be used in regression?
Yes you can! In your case, you’re talking about a binary dependent variable because it has only two levels (presumably), admitted and not admitted. In that case, you’d use binary logistic regression and it’s fine to use a binary (or categorical) independent variable.
