- What does the y -intercept on the graph of a logistic equation correspond to for a population modeled by that equation?Find the maximum likelihood estimator by getting the derivative and equating it to 0For linear regression, the standard error of estimate can be computed as the square root of O SS residual/(n-1). O SS residual/(n − 2). O SS regression/(n-1). SS Pregression/(n - 2).

Find (a) The likelihood function. (b) The log-likelihood function (c) the maximum likelihood estimator for the unknown parameter, andPlease help me find likelihood, log-likelihood and MLEs of two parameters, thank you.When we fit a logistic regression model with a single explanatory term, x, we often assume that logit (pi) Bo + ₁x₂ where, for the ith observation, p; is the probability of a trial being successful and *; is the value of the explanatory variable. Which of the following is a good reason for using the logit link function? We can't use more than one explanatory term unless we use this link function. It allows us to model nonconstant variance in the response variable. It ensures that the probability of success is between 0 and 1. It ensures that the variance of the response is the same for all observations.
- Fit a curve of the form g(x) = Ax-1 to the dataset using the Least Squares Method. Calculate the corrected values and the total squared error.We learned that wheat prices explain wheat acreage very poorly because the R-squared values are particularly low. Theoretically, our model might have done better if we had ensured that both time series (sown area as the dependent variable and wheat price as the independent variable) were stationary before running the model, thus eliminating the possibility of "spurious" results. Again model wheat sown area as a function of wheat price, but this time make sure the variables are stationary before running the model. Report your results fully; include a discussion of the R-squared of your model and the statistical significance of the dependent variable. Dataset: Year Spring wheat seeded acreage Wheat cost of production ($/acre) Spring wheat yield (bushels/acre) Spring wheat production (bu per acre) Wheat price ($/ tonne) Canola production (tonnes) Canola price ($/ tonne) Canola Seeded acreage 1982 4,000,000 167.9 34 136,000 165 399,200 260 850,000 1983 4,600,000 153.3 27.2…Weekly downtime of internet services from an internet service provider (in hours) has expected value 0.5 and variance 0.25.

Suppose also that Var(X) =18 and Var(Y) = 26 In this case, the total change in the value over these two days is given by X +Y. Do you have enough information to compute Var(X +Y)? If so, compute this value. If not, explain what additional information you need to do so.The pdf is given as follows: f(x) = { (1/6)e^(1/6x) ; x > 0 0; ew] (i) Find the mean and variance of X using the pdf.
