General description

The shiny application developed calculates the linear model, which best fits the given X and Y variables.

Then, the fitted model is represented in two ways, as a plot and as a text output.

Input

The application takes two inputs, X and Y values.

Note:

  • They must be both numbers, separated by ',' (commas).
  • They must have the same length.

E.g.: the input:

  • X values: 1, 2, 4
  • Y values: 3, 5, 6

will fit the points: (1,3), (2,5), (4,6)

Output

  1. Fitted linear model:

    • Intercept: The intercept of the fitted linear model.
    • Slope: The slope of the fitted linear model.

  2. Plot: The plot represents the points given by the user and the fitted linear model.

Example

The input:

  • X values: 1, 2, 3
  • Y values: 2, 3, 4

Will create the plot:

plot of chunk unnamed-chunk-1
