Generalized Linear Mixed Model (GLMM)

Generalized Linear Mixed Model(GLMM) is the sum of Generalized Linear Model and Linear Mixed Effect Model.

Generalized Linear Model (GLM)

GLM is application of Regression Analysis .

For examle, in regression analysis,
Y = a1 * x1 + a2 *x2 + b

Y = f( a1 * x1 + a2 *x2 + b )

Linear Mixed Effect Model (LME)

LME is also application of Regression Analysis .

General regression model uses 1 slope and 1 intercept. But LME uses more than 2 of them.

Slope is 1 - Intercept is more than 2

There are 3 examples.
Slope is more than 2 - Intercept is 1 Slope is more than 2 - Intercept is 1 Slope is more than 2 - Intercept is 1

Slope is more than 2 - Intercept is 1

Slope is more than 2 - Intercept is 1

Use of LME

1 Use of LME is not only the case, "More than 2 slopes or intercepts", but also "There are more than 2 data-sets measured repeatedly".

After puttin the categorical variable and giving categorical values for each set, we can use LME.

Common Point with Quantification Methods

Quantification Methods uses Dummy Variable .

It is the same way with LME.

Hierarchical Bayes model

GLMM is an application of classical regression analysis. If we need more complicated distribution model, Hierarchical Bayes model is a solution.

Hierarchical Bayes model is an application of Bayesian Statistics .

Software R

Example of R is in the page, Generalized linear mixed model by R .

Software R-EDA1

R-EDA1 can use generalized linear model, linear mixed model, and generalized linear mixed model.

Analysis as a set with a scatter plot

Select "Stratifeid_graph" and then "scatter" to use the variables you chose to draw the scatter plot, LMM (Linear Mixed Model), GLMM (Generalized Linear Mix) The result of the model) will appear below the scatter plot.

If only the result of GLMM is used, the R-squared (coefficient of determination: square of correlation coefficient) number is not calculated, so LMM is included. Also, in R-EDA1, an error occurs for some reason when writing the above R example, so I am making a model with an interaction term by the method of quantification type I. The step function is used to create a model with non-significant terms removed.

Analysis using many variables

When analyzing a set with a scatter plot, the variables used in the scatter plot are included in the model.

The ability to run GLM on all variables in a dataset is elsewhere.
