Returns the standardized residuals/errors of a given GLM.

## Syntax

**GLM_RESID **(**Y**, **X**, **Beta**, **Phi**, Lvk)

**Y**- is the response or the dependent variable data array (a one-dimensional array of cells (e.g., rows or columns)).
**X**- is the independent variables data matrix, so each column represents one variable.
**Beta**- are the coefficients of the GLM model (a one-dimensional array of cells (e.g., rows or columns)).
**Phi**- is the GLM dispersion paramter. Phi is only meaningful for Binomial (1/batch or trial size) and Gaussian (variance).
Value Phi Gaussian Variance. Poisson 1.0. Binomial Reciprocal of the batch/trial size). **Lvk**- is the link function that describes how the mean depends on the linear predictor (1 = Identity (default), 2 = Log, 3 = Logit, 4 = Probit, 5 = Log-Log).
Value **Lvk**1 Identity (Residuals ~ Normal distribution) ( **default**).2 Log (Residuals ~ Poisson distribution). 3 Logit (Residuals ~ Binomial distribution). 4 Probit (Residuals ~ Binomial distribution). 5 Complementary log-log (Residuals ~ Binomial distribution).

## Remarks

- The underlying model is described here.
- The GLM residuals are defined as follow: $$\left[\epsilon\right]= \left[Y\right] - g^{-1}(X\beta)$$
- GLM_RESID returns an array of size equal to the number of rows in the input response (Y) or explanatory variables (X).
- The number of rows in the response variable (Y) must equal the number of rows of the explanatory variables (X).
- The betas input is optional, but if the user provides one, the number of betas must equal the number of explanatory variables (i.e., X) plus one (intercept).
- For GLM with Poisson distribution,
- The values of the response variable must be non-negative integers.
- The dispersion factor (Phi) value must be missing or equal to one.

- For GLM with Binomial distribution,
- The values of the response variable must be non-negative fractions between zero and one, inclusive.
- The value of the dispersion factor (Phi) must be a positive fraction (greater than zero and less than one).

- For GLM with Gaussian distribution, the dispersion factor (Phi) value must be positive.
