Given the FlightDelay.csv file, use Naïve Bayesian Analysis model to determine whether the various flights experience delay or arrive at their destination on time.

We start by clicking the “install” on your R plot window (as shown below) to type and install the following packages: naivebayes, dplyr, ggplot2, and psych; one at a time.

After the installation of all the packages, load them into the memory through these commands:

> library (naivebayes)

> library (dplyr)

> install.packages(ggplot2)

> library (psych)

Next, we load the .csv file and check the statistical properties of the csv file as follow:

> setwd(“C:/RData”) # your working directory

> tumor <- read.csv(“FlightDelay.csv”) # loading the file

> str(FlightDelay) # check the properties of the file

. . . continue from here!

Important Note:

• You need to split your data into test-data (tdata) and validated-data (vdata).

• Use tdata to build Naïve Bayes’ model and use vdata to predict your model.

• The dependent variable (y) of the model is delay.

• The independent variables are dest, origin, carrier, deptime, weather, & dayweek.

• Show your conclusion.
