## What is the dependent variable in GLM?

Generalized Linear Model (GLM) helps represent the dependent variable as a linear combination of independent variables. Simple linear regression is the traditional form of GLM. Simple linear regression works well when the dependent variable is normally distributed. GLM comes in handy in these types of situations.

Can you have 2 dependent variables in multiple regression?

Yes, this is possible and I have heard it termed as joint regression or multivariate regression. In essence you would have 2 (or more) dependent variables, and examine the relationships between independent variables and the dependent variables, plus the relationship between the 2 dependent variables.

### Can I have multiple dependent variables?

It is possible to have experiments in which you have multiple variables. There may be more than one dependent variable and/or independent variable. This is especially true if you are conducting an experiment with multiple stages or sets of procedures.

How many dependent variables can there be in regression models?

one dependent
The interpretation of the coefficients is more problematic with independent variables measured at the nominal or ordinal level. Regression with only one dependent and one independent variable normally requires a minimum of 30 observations.

## Do we need to scale dependent variable?

Commonly, we scale all the features to the same range (e.g. 0 – 1). In addition, remember that all the values you use to scale your training data must be used to scale the test data. As for the dependent variable y you do not need to scale it.

Why is it acceptable to have multiple dependent variables?

Researchers in psychology often include multiple dependent variables in their studies. The primary reason is that this easily allows them to answer more research questions with minimal additional effort.

### When would you not use multiple linear regression?

Linear regression can only be used when one has two continuous variables—an independent variable and a dependent variable. The independent variable is the parameter that is used to calculate the dependent variable or outcome. A multiple regression model extends to several explanatory variables.

How do you know which variables to use in regression?

When building a linear or logistic regression model, you should consider including:

1. Variables that are already proven in the literature to be related to the outcome.
2. Variables that can either be considered the cause of the exposure, the outcome, or both.
3. Interaction terms of variables that have large main effects.

## How many dependent variables can you have?

A well-designed experiment normally incorporate one or two independent variables, with every other possible factor eliminated, or controlled. There may be more than two dependent variables in any experiment.

Which analysis is done when you have two dependent variables?

Explanation: Bivariate analysis investigates the relationship between two data sets, with a pair of observations taken from a single sample or individual.

### How do you select independent variables in regression?

Which Variables Should You Include in a Regression Model?

1. Variables that are already proven in the literature to be related to the outcome.
2. Variables that can either be considered the cause of the exposure, the outcome, or both.
3. Interaction terms of variables that have large main effects.

Should I scale the response variable?

Yes, you do need to scale the target variable. I will quote this reference: A target variable with a large spread of values, in turn, may result in large error gradient values causing weight values to change dramatically, making the learning process unstable.
