Question 1

To convert MSR/MSRes, or the F statistic, to accomodate R^2, you mustremember that MSR=SSR/k, MSRes is SSRes/(n-k-1), F statistic is MSR/MSRes, SSR/SSRes can be written as SSR/SST, and R^2 is SSR/SSRes or 1-SSRes/SST. multiply both the numberator and demoniator with the ones they are usually divided by, or SSR(n-k-1)/SSResk, then seperate them like so: SSR/SSres * (n-k-1)/k, then convert SSR/SSRes to SSR/SSRes+SSR, which R^2=SSR/(SSRes+SSR) or 0.7=SSR/(SSRes+SSR), then both sides are multiplied by SSRes+SSR to get 0.7SSRes+0.7SSR=SSR, which SSR is then subtracted by 0.7 SSR to get 0.3SSR, which is then 0.7SSRes=0.3SSR, where SSR is divided by SSRes and 0.7 is divided by 0.3 to get SSR/SSres=0.7/0.3 or 2.3. The given units of n=20 and k=5 are used to make (20-5-1)/5 to get 14/5 or 2.4. 2.3*2.4 obtains 6.44, which the result in pf then subtracts 1 to obtain the answer

(0.7-1)*((20-5-1)/5)
## [1] -0.84
pf(5, 14, 6.44)
## [1] 0.9756428
1-0.9756428
## [1] 0.0243572

Question 2

This is an R programming for developing a matrix seen in HW2, but for wine quality than engine efficiency. This will take the variable pH(x2), total SO2 content (x3), color density (x4), polymeric pigment color (x6), anthocyanin color, (x7), total anthocyanins (x8) and density of ionization (x9) After developing X, W is created through the unit length scaling equations, which involve using xij for each of the 32 by 7 x answers for the matrix and -xi that is the mean of those x column answers (e.g. put the results of each x1 answer in the equation, while the mean is the mean of x1). I will perform manual unit length scaling and then do the correlation check afterwards This is (ULS) of X2

Next, W will be created with the unit length scaling results

W<-cbind(1, c(1,-1,1,1,1,1,1,-1,1,-1,1,-1,1,1,1,1,-1,-1,1,1,-1,1,-1,-1,-1,-1,1,-1,-1,1,-1,-1), c(-1,-1,-1,1,-1,-1,-1,-1,-1,1,-1,1,-1,1,-1,-1,-1,-1,-1,-1,1,-1,1,1,-1,1,-1,1,1,-1,-1,1),c(1,1,1,1,1,1,-1,-1,-1,-1,-1,-1,-1,-1,-1,1,1,1,1,1,1,-1,1,-1,1,-1,-1,-1,1,1,-1,-1), c(1,1,1,1,1,1,-1,-1,-1,-1,-1,-1,-1,-1,1,1,1,1,1,1,1,-1,1,-1,1,-1,-1,-1,1,1,-1,1), c(-1,-1,1,-1,1,1,-1,-1,1,-1,-1,1,1,-1,1,1,-1,-1,1,-1,1,1,-1,-1,-1,-1,-1,1,-1,1,-1,1), c(1,1,1,1,-1,1,-1,1,-1,-1,-1,-1,-1,-1,1,1,1,1,1,1,1,-1,1,-1,1,-1,-1,-1,1,-1,-1,-1))

Question 3

Now the length scaling correlation matrix ofW^TW is processed and compared to the correlation matrix of X to show similarities and if it indicates signs of colinerarity The results obtained show no similarity to each other, with the correlation of matrix X being much closer to the W matrix than the correlated WTW matrix. Most likely the result of error, but could also indicate that the matrices don’t have as musch in common since they are each dedicated to a completely different part of the wine’s quality
