--- Problem: When I do an FFT of a known SINE wave, I don't get a perfect amplitude peak at my known frequency. Response: When you look at the result of an FFT, you can think of it as looking at the 'true' FFT through a picket fence. Changing the picket spacing or shifting...
It is demonstrated that the customary unweighted linear regression analysis places undue emphasi on data drawn from the foot and head of the wave. A technique for avoiding this by using weighted least-squares is advocated and an algorithm to perform the analysis is presented and evaluated....
True or False: If the slope of a simple linear regression line is statistically significant, then the correlation will also always be significant. Fit the model to the data using simple linear regression. Give the least squares prediction equation For the given (X...
(a) Find the amplitude of the wave given from the graph of a wave that has joules as the y-axis and time on the x-axis. (b) Find the wavelength given from the graph below.a) Using the distance-versus-time graph below, determine the instantaneous speed of the bicycle at ...
Briefly, upon selection of scattered points, they were subjected to computerization, by regression, to reveal the piece of electrocardiogram (ECG) containing an R wave (QRS complex). Then ECG was analyzed to diagnose the cardiac rhythms. In conclusion, t-RR is a novel methodology which helps ...
When a PAC fires with a shortened RR-interval (ti−1), returning cycle would be prolonged if the sinoatrial node (SA node) is not electrical penetrated by the electrical wave of PAC. The electrical wavefronts of PAC and the SA node collide somewhere in the atrium, and the returning ...
Statistical methods such as simple and multiple linear regression (LR) are practical to compute; however, they must meet basic assumptions like data normality and variance homogeneity, among others. The results are satisfactory with few field samples and various spectral variables, which makes them ...
