# First simulated data for the simple linear regression model

`SLM1.Rd`

First data used in example 4 of Salmerón, García and García (2024) (subsection 4.4) on the special case of the simple linear model.

## Usage

    data("SLM1")

## Format

A data frame with 50 observations on the following 3 variables:

`y1`

  Dependent variable simulated as y = 3 + 4*V + u where u is normally distributed with a mean of 0 and a variance of 2.

`cte`

  Intercept.

`V`

  Simulated from a normal distribution with a mean of 10 and a variance of 100.
