Run a Paired Samples t Test. To run a Paired Samples t Test in SPSS, click Analyze Compare Means Paired-Samples T Test. The Paired-Samples T Test window opens where you will specify the variables to be used in the analysis. All of the variables in your dataset appear in the list on the left side.
A fixed point is a point that does not change upon application of a map, system of differential equations, etc. In particular, a fixed point of a function f(x) is a point x_0 such that f(x_0)=x_0. (1) The fixed point of a function f starting from an initial value x can be computed in the Wolfram Language using FixedPoint[f, x].
The solution set for the equations x â y = â1 and 3x + y = 9 is the single point (2, 3). A solution of a linear system is an assignment of values to the variables x1, x2, ..., xn such that each of the equations is satisfied. The set of all possible solutions is called the solution set. A linear system may behave in any one of three possible ways: The system has infinitely many solutions.
