C. Explore the function of getLDS.

D. Generate 5 random numbers from binomial distribution with 10 trials and 0.2 probability.

Question 2 -

Find a r package used for plotting Venn diagram. Provide examples for the following:

  • try two-way with internal labels and proportional circle size.
  • three-way with internal labels.
  • try three-way with internal labels and proportional circle size.

Question 3 -

A. Supervised vs. unsupervised learning. Simple nnet vs. deep learning nnet.

B. How to evaluate the models.

Question 4 -

A. Provide examples of using "." as a special character and a literal character.

B. Provide examples of using "\" as a special character and a literal character.

C. Use example to compare "[]" vs "()".

D. Provide examples of using quantifiers (+, *, ?, {num}, {num1, numb2}, {num,}).

E. Provide examples of using character classes ("\D","\w").

Question 5 -

A. Make a summary table for t-test.

For a classic t-test (variances assumed equal)

t.test(var1, var2, var.equal=T)

Id variances are assumed unequal use the Welch procedure

t.test(var1, var2)

If you have paired data run the paired version

t.test(var1, var2, paired = T)

B. Explain error from sample (2, 5).
