How Disease is Spread by Vectors In medical science or biology‚ a vector refers to an agent (microbes‚ animals or person) that does not cause disease by itself but helps in transmitting the pathogens that cause disease from one host to another. In this sense‚ the host could be humans‚ animals or plants. These vectors have contributed to the epidemic of so many diseases. Different diseases are transmitted by different vectors but some ailments share common vectors. For instance female anopheles

Vector aeromotive corporation case study Vector Aeromotive Corporation was a company which designed‚ manufactured and sold exotic sports cars. Vector was the only U.S.-based manufacture of exotic sports cars‚ and his major competitors were Ferrari and Lamborghini. Gerry Wiegert is the President and founder of this company. In 1987‚ the board of directors was formed with three directors. This case shows events happening between the board and President Gerry. In March 1993‚ the company’s financial

Always start with scatter plot to see if the data is linear (i.e. if the relationship between y and x is linear). Next perform residual analysis and test for violation of assumptions. (Let y = arterial oxygen and x = blood flow). twoway (scatter y x) (lfit y x) regress y x rvpplot x 2. Since regression diagnostics failed‚ we transform our data. Ratio transformation was used to generate the dependent variable and reciprocal transformation was used to generate the independent variable.

linear regression In statistics‚ linear regression is an approach to model the relationship between a scalar dependent variable y and one or more explanatory variables denoted X. The case of one explanatory variable is called simple linear regression. For more than one explanatory variable‚ it is called multiple linear regression. (This term should be distinguished from multivariate linear regression‚ where multiple correlated dependent variables are predicted‚[citation needed] rather than a single

decision variables‚ create a formula in a cell to represent the objective function and create a formula in a cell for each constraint left hand side. Once the model is implemented in a spreadsheet‚ next step is to use the Solver to find the solution. In the Solver‚ we need to identify the locations (cells) of objective function‚ decision variables‚ nature of the objective function (maximize/minimize) and constraints. Example One (Linear model): Investment Problem Our first example illustrates how to allocate

$5‚000 for each acre of wheat and $3‚000 for each acre of barley‚ then the total profit the farmer can earn is 5000*x + 3000*y. let p = total profit that can be earned. your equation for profit becomes: p = 5000x + 3000y that’s your objective function. it’s what you want to maximize the constraints are: number of acres has to be greater than or equal to 0. number of acres has to be less than or equal to 8. amount of pesticide has to be less than or equal to 10. your constraint equations are:

Linear Least Squares Suppose we are given a set of data points {(xi ‚ fi )}‚ i = 1‚ . . . ‚ n. These could be measurements from an experiment or obtained simply by evaluating a function at some points. You have seen that we can interpolate these points‚ i.e.‚ either find a polynomial of degree ≤ (n − 1) which passes through all n points or we can use a continuous piecewise interpolant of the data which is usually a better approach. How‚ it might be the case that we know that these data points should
