Question 25 (1 point) Listen What happens when you overfit a regression model? The model captures too much of the random variation in the sample data and fails to predict accurately for the population. The p-value for the F-test of overall significance is greater than 0.05. So many variables are added to the model that the Adjusted R² value exceeds 1 None of the relationships in the model are found to be statistically significant.

We want to build a regression model and have many observations and many predictors. (a) From a computational point of view, which of these two model building algorithms are preferable: best subset selection or forward stepwise selection? (b) True or false and explain: Best subset selection will result in a smaller prediction error than forward stepwise selection because every model that is considered in forward stepwise selection is also considered in best subset se
The following is true about sensitivity: Group of answer choices a) The output of the model is said to be inversely sensitive if the output of the model changes a small amount for a large change in an input variable b) Sensitivity is not an important concept in modeling c) It can help the modeler tell, on a relative basis, what are the important variables d) A variable is considered NOT very sensitive if a small change in the variable results `in a large change in the output of the model.
Mary: "Before we run the multivariate linear regression, feature scaling should be performed." Give one reason to support Mary's idea. Moreover, should we perform feature scaling before or after the gradient descent?
Computer Science Compute the following values You're performing a simple linear regression, whereby you check whether or not the hardness of synthetic bone for the prothesis x lines up to the target, specified hardness for each datum given by y. Unfortunately, someone spills ink all over your beautiful regression table. As a result, you can only read the following, though you also do recall that the data set had exactly 32 observations, and that we are using the default alpha for statsmodels of a = 0.05. coef std err P > \t| [0.025 0.975] const MISSING 1.438 -0.346 MISSING -3.433 2.439 0.9223 0.136 MISSING 0.000 0.644 MISSING Compute the following values, using scipy.stats syntax if being exact is not possible. A) What is the correct numeric value for "MISSING" from the "P > [t" column of "constant"? B) What is the correct numeric value for "MISSING" from the "coef" column of "constant"? C) Because the data was meant to compare a target hardness y to a desired hardness x, you decide…
Why don't we use the ordinary least square to learn a linear regression model for a classification problem (i.e., learning to fit the label of 0 or 1)? Select one: a. Linear regression cannot output value in a probability range. b. OSL will learn a bad linear regression model for a classification. c. Yes, we can. Linear regression is the same as logistic regression. d. Linear regression outputs continuous variable.
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…
