Comment on how well the model fits the data: One way to see if the model fits the data or not is to see the p-value of the ANOVA table. If the p-value is smaller than 5%, it fits the data well. Otherwise, it does not fits, meaning, the severance pay has little relations of all these independent variables. What is the p-value of the model? Tip: If the answer is 1.2345E-5, means: 0.000012345. for 4 decimals, the answer is...
can somebody please help me with the question quickly I really need help with this, choose a country and research population data in order to fill out the table below.
2. Choose a country and research population data in order to fill out the table beloa. Copy the population numbers counted each five years, as shown in the data base, for the years from 1950 to 2000 . Add a column, \(t\), measuring years șince 1945 .b. What is the country you selected? In what part of the world is it? What is the magnitude of its population numbers? \(\left(100,000^{\circ} \mathrm{s}\right.\), millions, hundred millions, billions?) Is it growing or shrinking...

1. In the simple regression model y = + β1x + u, suppose that E (u) 0. Letting oo-E(u), show that the model can always be rewrit ten with the same slope, but a new intercept and error, where the new error has a zero expected value 2. The data set BWGHT contains data on births to women in the United States. Two variables of interest are the dependent variable, nfan birth weight in ounces (bught), and an explanatory variable,...

can you please solve the question ?
We try to solve the binary classification task ilustrated in the below figure with a simple linear log istic regression model Notice that the training data can be separated with zero training error with a linear separator. Consider training regularized linear logistic regression models where we try to maximize for very large . The regularization penalties used in penalized conditional lag likelihood estimation are -Cu, where(0,1.2). In other words, only one of the...
