What is the difference between curve fitting and regression?
curve fitting is a very difficult and time wasting method while regrresion is more to use as compare to curve fitting
How do you estimate the best fit of curve?
You always use some model (i.e. function) to fit experimental curve. If you do not know the kind of curve (linear, parabola, Gauss, etc.) you can try to fit with different functions and then compare the residual sum of squares and coefficient of determination of those fit functions. I use MagicPlot for curve fitting, you can try to find something in MagicPlot on-line help.
How is curve fitting used in mathematics?
Curvie fitting is used in mathematics to find a mathematicalmodel that fits your data. The curve fit fins the specific parameters which make that function match your data as closely as possible.
What is the purpose of making a standard curve?
The values of many curves cannot be calculated analytically: the process requires painstaking numerical estimation. The values of a standard curve can be calculated once and published for ready reference. This means that, given any other curve in the same family, it is possible to transform it to the standard curve and the reference values can be used.
When the larger values of the standard deviation result in a normal curve that narrower and more peak?
Smaller

How can you find a least square trend in a equation?
When given a set of data where the independent variable is time, it is possible to use statistical techniques to find a line (or curve) of best fit. One of the ways to do this is to minimise the square of the the differences between the actual values which are observed and the values that are predicted by such a curve (fitted values). The slope of this line or of the tangent to the curve at any point, is the least squares trend.A statistical explanation of the theory or the calculations required are too much for the pathetic browser that we are required to use.

Explain conceptions of root means square?
It's a kind of average. Specifically, it means that you square a number of values, take their average, and take the square root again. In the case of continuous values - such as electrical voltages or currents, an area where RMS is frequently used - integration must be used. As an approximation, you can imagine that the curve that represents the signal is divided into lots of small intervals.
How is definite integral connected to area under the curve?
If the values of the function are all positive, then the integral IS the area under the curve.
In a normal curve what three values are equal?
mean, median and mode
What has the author P G Guest written?

What has the author Ian Grant Sinclair written?

What is the application of curve fitting in enggineering?
the technique of curve fitting is used in many engineering streames and one of its important applications is that it is also used in industries to study the performance of the company and also to predit the future performence of the company. it very much helps in finiding out operational profit margin (OPM).
If all of the data values in the class were compiled in a giant histogram and a curve was drawn over the graph where should the highest point on the curve occur?
the curve should be located in the center of the graph.
