Inference for categorical data - DATA606 - LAB 6
Getting Started Load packages In this lab, we will explore and visualize the data using the tidyverse suite of packages, and perform statistical inference using infer. The data can be found in the companion package for OpenIntro resources, openintro. Let’s load the packages. library(tidyverse) library(openintro) library(infer) The data You will...

DATA 607 - Project 2 - Dataset 1.3
Project 2 - Data Transformation The goal of this assignment is to give you practice in preparing different datasets for downstream analysis work. Your task is to: Choose any three of the “wide” datasets identified in the course Slack channel. (You may use your own dataset; please don’t use my Sample Post dataset, since that was used in your ...

Let X1, X2, . . . , Xn be n mutually independent random variables, each of which is uniformly distributed on the integers from 1 to k. Let Y denote the minimum of the Xi’s. Find the distribution of Y. P(Y≤y) = 1 − P(Y>y) P(Y≤y)= 1 − P(min(X1, X2,…, Xn) > y) P(Y≤y)= 1 − P(X1 > y, X2 > y,…, Xn > y) P(Y≤y)= 1 − ((k-y)/k) ^n Then...

DATA607 - Assignment 5 – Tidying and Transforming Data
Assignment – Tidying and Transforming Data Your task is to: (1) Create a .CSV file (or optionally, a MySQL database!) that includes all of the information above. You’re encouraged to use a “wide” structure similar to how the information appears above, so that you can practice tidying and transformations as described below. (2) Read the i...

Foundations for statistical inference - Confidence intervals - DATA606 - LAB 5B
If you have access to data on an entire population, say the opinion of every adult in the United States on whether or not they think climate change is affecting their local community, it’s straightforward to answer questions like, “What percent of US adults think climate change is affecting their local community?”. Similarly, if you had demog...

Foundations for statistical inference - Sampling distributions - DATA606 - Lab 5A
In this lab, you will investigate the ways in which the statistics from a random sample of data can serve as point estimates for population parameters. We’re interested in formulating a sampling distribution of our estimate in order to learn about the properties of the estimate, such as its distribution. Setting a seed: We will take some random ...

A bag contains 5 green and 7 red jellybeans. How many ways can 5 jellybeans be withdrawn from the bag so that the number of green ones withdrawn will be less than 2? choose(5,5)*choose(7,0)+choose(5,4)*choose(7,1) ## [1] 36 A certain congressional committee consists of 14 senators and 13 representatives. How many ways can a subcommittee of 5 be f...

DATA605 Assignment #5
Bayesian 1.A new test for multinucleoside-resistant (MNR) human immunodeficiency virus type 1 (HIV-1) variants was recently developed. The test maintains 96% sensitivity, meaning that, for those with the disease, it will correctly report “positive” for 96% of them. The test is also 98% specific, meaning that, for those without the disease, 98% ...
