What s the difference between and in lm in R

Question

I should note at the outset of this piece that I have very little experience with R and only a very fundamental understanding of statistics. If I use the wrong terminology, I wish to apologise (and that I most definitely need to do more reading).

One of the 17 variables in the dataset I'm now looking at is the dependent variable, and the other 16 are independent variables. I have to decide which linear model between these variables is "better."

So, this is what I have to work with:

MA1 - lm(step

the formula as.formula(paste(colnames(NLCD)[1], "",

Collapse = "*" and paste (colnames(NLCD)[c(2:17)]

Data = NLCD (),

))

So, NLCD is the name of the dataset, while MA1 is a model. I'm confused as to whether use "*" or "+" for the stepwise regression. RStudio freezes when I run the model with the "*"

Answer 1

Lm is a fitting method for linear models.

The following syntax is used by this function:

formula, data, and lm

where:

formula: The linear model's formula (for instance, y = x1 + x2)

information: The title of the data frame containing the information

2. GLM - Generalized linear models are fitted using this.

The following syntax is used by this function:

the formula glm(formula, family=gaussian, data,...)

where:

formula: The linear model's formula (for instance, y = x1 + x2)

the statistical family to be applied while fitting the model. Gaussian is the default, although there are also alternatives for binomial, poisson, and Gamma distributions.

information: The title of the data frame containing the information

Keep in mind that the family argument used by the glm() method is the only distinction between these two functions.
