Module 9: Tabulating Tabular Data in R

 Hi everyone! 

This week's assignment focuses on using R to make tables from data frames. We also explore adding sum totals for both rows and columns in our contingency tables and creating proportion tables.

1.
Generate simple table in R that consists of four rows: Country, age, salary and purchased.

2. Generate contingency table also know as r x c table (Chapter 7, p.135) using mtcars dataset.

>assignment9 <- table(mtcars$gear, mtcars$cyl, dnn=c("fill out here")

2.1 Add the addmargins() function to report on the sum totals of the rows and columns of assignment9 table
>addmargins(assignment9)


2.2 Add prop.tables() function, and report on the proportional weight of each value in a assignment9 table


2.3 Add margin = 1 to the argument under prop.table() function, and report on the row proportions found in assignment9 table.

Module 10: Varying Multivariate Regression

Image
  Hi everyone!  This week we dive into a more complex regression analysis than the linear regression we have done. Before we had one predictor variable and one outcome variable. In multivariate multiple regression, we have multiple predictor(or independent) variable but one outcome variables we are analyzing. The formula looks like  y = b 1 x 1  + b 2 x 2  + …   + b n x n  + error.  We will look into the relationships between the variables collectively using ANOVA analysis and individually through linear regression (lm) to understand which variables are contributing to the significance of the relationship. R sqaured will be an important factor to look into because it shows the amount of variation in dependent variable explained by the regression, thus a larger R squared indicates the predictor is more precisely able to predict outcome.  9.1.  Conduct ANOVA (analysis of variance) and Regression coefficients to the data from cyst...

Final Project: Serially looking at your Cereal Choices

Image
  Hi everyone!  Almost everyone starts their mornings with a nice bowl of cereal. In the grocery aisle, you choose a box of cheerios and chocolate puffs. However, your decision to buy that cereal may not have been completely your choice at all. You just picked from the options that were conveniently placed in front of you.  My project will analyze the relationship between the shelves cereals are placed on to the sugar, fiber, and calories of that cereal. Do the ingredients of cereals, either healthy or sugary, play a role in what shelf cereals are placed on and their ratings?  Two Part Analysis  Do the ingredients s ugar, calories, and fiber content have a true mean difference with that cereal's placement on shelf 1,2, or 3 (counting from the ground)? I will use boxplots to understand each ingredients distribution in the shelves and perform ANOVA tests to determine if each ingredient is significant for the placement of the the cereal. ANOVA i...

Module 12: Timely Time Series

Image
  Hi everyone!  This week we are looking into time series where we dive into the past to predicate the future! Our goals in using time series analysis include identifying patterns in the periodic data, predict short term trends, and model these findings. Time series data has components with the most common being the trend and seasonal components. In our data if we see a lot of fluctuation around a common line or "zone", we can focus on methods to understand the trend component like simple exponential smoothing. If more of the data fluctuates based on periodic fluctuations we use methods like decomposing and seasonally adjusting. We will be focusing on exponential smoothing in our data today! This is useful for short term forecasting with an alpha coefficient between 0 to 1 indicating the weight of the moving average. A smaller alpha means the data is getting more smoothed while a higher alpha indicates less smoothing.  Let's get started! The table...
