Multiple Linear Regression Analysis
In a study of housing demand, the county assessor is interested in developing a regression model to estimate the market value (i.e., selling price) of residential property within her jurisdiction. In... More > addition, the assessor feels that there may be other important variables that will affect the market value of the house such as the size of the house, number of rooms, age and whether the house has an attached garage. These data for 15 randomly selected houses arc shown in the attached table.< Less
Application of System of Two Equations
"Suppose Bob owns 2,000 shares of Company X and 10,000 shares of Company Y. The total value of Bob's holdings of these two companies is $340,000.
Suppose Frank owns 8,000 shares of Company X... More > and 6,000 shares of Company Y. The total value of Franks holdings of these two companies is $340,000.
a. Write equations for Bob and Frank's holdings. Use the variables X and Y to represent the values of shares of Company X and Company Y.
b. Solve for the value of a share of Company X and Company Y. Show your work so you can get partial credit even if your final answer is wrong.
MATLAB-program for Solving the Systems of First and Second Order Linear Differential Equations with Jump Perturbations
Ships in 3-5 business days.
We present a program for solving the systems of first and second order linear differential equations with perturbations, having a stepped form, or form of the Dirac function. The known perturbations... More > may be presented in tabular form. The result will be given in the form of power series coefficients. The system should not be solved with respect to the higher derivative. The method makes it possible to vary the length of the power polynomial (result), accuracy and duration calculations. Compared to standard MATLAB functions the form of initial and resulting data is more convenient. The calculation programs and tests is developed within the MATLAB-6 system and the program code is open.< Less
