R is a language and environment for statistical computing and graphics. It is a GNU project which is similar to the S language and environment which was developed at Bell Laboratories (formerly AT&T, now Lucent Technologies) by John Chambers and colleagues. R can be considered as a different implementation of S. There are some important differences, but much code written for S runs unaltered under R.Why are statistical programming languages important to data scientists? What are some advantages and disadvantages the R programming language has over the other main statistical programming languages (i.e. Python, SAS, SQL)?Discussion Length (word count): At least 250 words (not including direct quotes).References: At least three peer-reviewed, scholarly journal references.

This assignment provides an opportunity to develop, evaluate, and apply bivariate and multivariate linear regression models. Resources: Microsoft Excel®, DAT565_v3_Wk5_Data_File Instructions:  The Excel file for this assignment contains a database with information about the tax assessment value assigned to medical office buildings in a city. The following is a list of the variables in the database: FloorArea: square feet of floor space Offices: number of offices in the building Entrances: number of customer entrances Age: age of the building (years) AssessedValue: tax assessment value (thousands of dollars) Use the data to construct a model that predicts the tax assessment value assigned to medical office buildings with specific characteristics. Construct a scatter plot in Excel with FloorArea as the independent variable and AssessmentValue as the dependent variable. Insert the bivariate linear regression equation and r^2 in your graph. Do you observe a linear relationship between the 2 variables? Use Excel’s Analysis ToolPak to conduct a regression analysis of FloorArea and AssessmentValue. Is FloorArea a significant predictor of AssessmentValue? Construct a scatter plot in Excel with Age as the independent variable and AssessmentValue as the dependent variable. Insert the bivariate linear regression equation and r^2 in your graph. Do you observe a linear relationship between the 2 variables? Use Excel’s Analysis ToolPak to conduct a regression analysis of Age and Assessment Value. Is Age a significant predictor of AssessmentValue? Construct a multiple regression model. Use Excel’s Analysis ToolPak to conduct a regression analysis with AssessmentValue as the dependent variable and FloorArea, Offices, Entrances, and Age as independent variables. What is the overall fit r^2? What is the adjusted r^2? Which predictors are considered significant if we work with ?=0.05? Which predictors can be eliminated? What is the final model if we only use FloorArea and Offices as predictors? Suppose our final model is: AssessedValue = 115.9 + 0.26 x FloorArea + 78.34 x Offices What wouldbe the assessed value of a medical office building with a floor area of 3500 sq. ft., 2 offices, that was built 15 years ago? Is this assessed value consistent with what appears in the database? For more information on Assessment Value read this: https://en.wikipedia.org/wiki/Assessment

For museums, raising and maintaining public interest in their ancient art collections has always been a challenge. But now, with the COVID-19 crisis, it’s even more important, in order to counteract the decrease in public awareness due to the loss of visitors to their galleries. If you go online and visit their website, you’ll find that Museums have reacted and are finding new and innovative ways of staying in contact with their patrons and potential future visitors. Discuss the strategies for staying in touch / raising public interest/awareness of at least three museums anywhere in the world that have art collections from the ancient Near East to Late Antiquity, i.e. Ancient Mesopotamia /  Iran, Levant, Greco-Roman, Parthian or Sasanian eras, Early Christian / Byzantine art of the Middle East and/or Islamic art from anywhere around the Mediterranean or the Middle East.  Discuss what online programs or web sites or other resources/activities each of these museums have implemented to create or keep interest in their ancient art collections either before or in response to the pandemic. How you visualize that online programs/websites / resources will impact the museum’s future online presence or its in-person visitors as either relate to their ancient art collections and galleries? Format: 6 double-spaced pages, not including bibliography or images. 1″ margins, 12-point font. You do not need to include images, but if you do, they must be at the end and not part of your text.Include a bibliography: Where available you should list:    Author of message or article            Year that the site was published/last updated (in round brackets).            Title of message or article or page (in single quotation marks).            Title of the internet site (in italics).            Day/month of posted article / message (where available)            Available at: URL.           (Accessed: date).
