In this exercise use the Peruvian blood pressure data set,
provided in the file peruvian.txt. This dataset consists of
variables possibly relating to blood pressures of n = 39 Peruvians
who have moved from rural high altitude areas to urban lower
altitude areas. The variables in this dataset are: Age, Years,
Weight, Height, Calf, Pulse, Systol and Diastol. Before reading the
data intoMATLAB, it can be viewed in a text editor.
This question involves the use of multiple linear regression...

Exercise 2. Consider the iris data set. (a) Fit a linear regression model for Sepal.Width using Sepal.Length and Species as predictors. Recall that Species is a categorical variable with 3 levels (setosa versicolor, and virginica). Use summary) to print the results. What is the base- line level for Species in the model? (b) Fit a linear regression model for Sepal.Width using Sepal.Length, Species, and the interaction between Sepal.Length and Species as predictors. Use summary ) to print the results. (c)...

For Questions 4-11, use the swiss dataset,
which is built into R.
Fit a multiple linear regression model with
Fertility as the response and the remaining
variables as predictors. You should use ?swiss to
learn about the background of this dataset.

peruvian.txtProblem 1 (explore the data):In this exercise use the Peruvian blood pressure data set, provided in the file peruvian.txt (A NOTE for repeat students: The data is different from the data I shared last year.). This dataset consists of variables possibly relating to blood pressures of n = 30 Peruvians who have moved from rural high altitude areas to urban lower altitude areas. The variables in this dataset are: Age, Weight, Height, Pulse, Systol and Diastol. Before reading the data into MATLAB, it can be viewed in a...

Linear Algebra
To fit data to an exponential model like y = AeKt, we first use a logarithm to linearize it: . n y n A k t Since A is a constant, so is ln A, and we can write this generically as ln y = co + cit. The table below shows the years different planes were first produced, along with how many displays (gauges, screens, etc.) were present in the cockpit. Year Introduced, y (Year after 1900)...

Question 2 (Modified from Sleuth 7.27) Black wheatears, Oenanthe leucura, are small birds of Spain and Morocco. Males of the species demonstrate an exaggerated sexual display by carrying heavy stones to nesting cavities. Different males carry somewhat different sized stones, prompting a study of whether larger stones may signal a higher health status. M. Soler et al. (1999) calculated the average stone mass (grams) carried by each of 21 male black wheatears, along with T-cell response measurements reflecting their immune...
