The following figure depicts the decision boundary for the logistic regression model built to predict preference for light beer vs. regular beer (PREFERENCE = Light is the success or positive class). The explanatory variables are INCOME and AGE. INCOME has a positive coefficient and AGE has a negative coefficient. Predictions are made based on the depicted decision boundary.

An independent t-test analysis compares a randomly assigned group of 16 participants who received a psychotherapy intervention on their changes in thought suppression to a control group (n=16) who received the treatment later. Thought suppression is measured, and high scores represent higher perceived thought suppression. How should the hypotheses be written for the given test? O A Ho: Hosychotherapy Hcontrol O B.

Question 48. Let us return to the Titanic data set. We now have learned several models and want to choose the best one. We used three different methods to validate these models: The training error rate (apparent error rate), the error rate on an external test set and the error rate estimated by a 10-fold cross validation. Training Error | Error on the test set | Cross Validation Error 0.18 Learner Decision Tree 0.22 0.21 Random Forest 0.01 0.10 0.12 1-Nearest-Neighbour 0.18 0.19 Which of the following statements are correct? a) 1-Nearest-Neighbour has a perfect training error and hence it should be used here. b) Random Forests outperforms both 1-Nearest-Neighbour and the Decision Tree in terms of prediction error. c) Not just in this case, but in general, Cross Validation is the better validation strategy and should always be preferred over the error on a single test set. d) Not just in this case, but in general, Decision Trees always perform worse than Random Forests.
The stand rental system is going to be used by any company to search for stands, either by prices, by prices, or by types. If there is any interest then the company will request a quotation through the system. This request will be assessed by a salesman of INSIGHTS. The salesman will issue a quotation accordingly. In the case the prices are convenient, the company will reserve the stands that it is interested in. The company has three days to pay the costs of the stands. The costs are obtained from the invoice generated by the salesman. The company can cancel its reservation any time. Furthermore, before the starting of the event, an employee of INSIGHTS with the role of supervisor will generate a report about the companies that paid the fees and the current setup of the exhibition. The supervisor will also issue the necessary reminders to the companies to bring their equipment as well as bring their promotion documents to the site of the exhibition. In order to implement the expected…
This is a binary classification problem, y has two values (0 or 1), and X (feature) has three dimensions. • Use a logistic regression model to project X to y (classify X into two categories: 0 or 1). • The initialization is: w1 = 0, w2 = 0, w3 = 0, b = 0, Learning rate is 2. • You must use Gradient Descent for logistic regression in this question. • The regression should stop after one iteration. Calculation process and formulas must be included in your answer! You must answer this question by manual calculation, but not programming.

Assume the following simple regression model, Y = β0 + β1X + ϵ ϵ ∼ N(0, σ^2 ) Now run the following R-code to generate values of σ^2 = sig2, β1 = beta1 and β0 = beta0. Simulate the parameters using the following codes: Code: # Simulation ## set.seed("12345") beta0 <- rnorm(1, mean = 0, sd = 1) ## The true beta0 beta1 <- runif(n = 1, min = 1, max = 3) ## The true beta1 sig2 <- rchisq(n = 1, df = 25) ## The true value of the error variance sigmaˆ2 ## Multiple simulation will require loops ## nsample <- 10 ## Sample size n.sim <- 100 ## The number of simulations sigX <- 0.2 ## The variances of X # # Simulate the predictor variable ## X <- rnorm(nsample, mean = 0, sd = sqrt(sigX)) Q1 Fix the sample size nsample = 10 . Here, the values of X are fixed. You just need to generate ϵ and Y . Execute 100 simulations (i.e., n.sim = 100). For each simulation, estimate the regression coefficients (β0, β1) and the error variance (σ 2 ). Calculate the mean of…

Investigators evaluated the effect of education (E1-1 if college or more, E2=1 if Masters degree or more, E1-E2=0 if less than college), Mother's Education (M=1 if college or more, O otherwise), and age (A, continuous, in years) on employment status (yes/no) using the following Logistic regression model: Logit= a + B1 E1+B2*E2 + B3*A + B4*M + B5*A*M SAS was used to create the following estimates: a= -2, B1-0.2, B2-0.4, B3-0.1, B4-0.3, B5=0.02. Calculate the odds that a 25 year old with just a college degree whose mother had a college degree is employed. Enter the odds to three decimal places.
What is the code in Stata for this question? Run the linear regression given by wages = β0 +β1education+β2workexp+β3unionmember +β4south+ β5−9occupation + β10female + u where wages=hourly wage in US dollars; education=years of schooling; workexp=years of work experience; unionmember=a dummy variable equal to ”1” if a person is a union member, and ”0” otherwise; south=a dummy variable equal to ”1” if a person lives in the south, and ”0” otherwise; occupation=a categorical variable equal to ”1” if a person’s occupation is ”management”; ”2” if it is ”sales”; ”3” if it is ”clerical”, ”4” if it is ”service”, ”5” if it is ”professional” and ”6” if it is ”other”. Please make sure to use ”other” as the base category; female =a dummy variable equal to ”1” if a person is female, and ”0” if a person is male.

In a recent study on world happiness, participants were asked to evaluate their current lives on a scale from 0 to 10, where O represents the worst possible life and 10 represents the best possible life. The responses were normally distributed, with a mean of 5.3 and a standard deviation of 1.9. Answer parts (a)-(d) below. (a) Find the probability that a randomly selected study participant's response was loss than 4. The probability that a randomly selected study participant's response was lons than 4 is (Round to four decimal placos as needed.)
In a linear classifier, there can be multiple linear models that can perfectly classify the training data points. SVM would prefer a model that has maximum margins from the data points between both classes. Select one: A. True B. False
