Beyond these assumptions, several other statistical properties of the data strongly influence the performance of different estimation methods: The following are the major assumptions made by standard linear regression models with standard estimation techniques e. The b variable is the y intercept - the point where the line crosses the y axis.

Referring to the figure, you can see that where the line crosses the x-axis, the y-coordinate is zero.

Lack of perfect multicollinearity in the predictors. Read more about e. I have taken the extensive amount of material I developed and made it available on this website.

Not the velocity of the wave, by the way. Which would be okay if I gave it a kick to start it from rest, but what if I release the mass from rest at a point away from equilibrium?

Interactive Tutorial Using Java Applet Click on the button above "click here to start" and maximize the window obtained. Think what this situation means: Nearly all real-world regression models involve multiple predictors, and basic descriptions of linear regression are often phrased in terms of the multiple regression model.

What will happen if we let this system evolve until its behaviour is stable? We can try this already. With each topic, the teacher explains the concept, and usually walks through a few sample problems. And it is FREE! To quote just one limit: The solutions have now been boxed and many explanations are more thorough.

If the experimenter directly sets the values of the predictor variables according to a study design, the comparisons of interest may literally correspond to comparisons among units whose predictor variables have been "held fixed" by the experimenter.

We now simply draw the line through the two points as in Fig 1. So we decided to offer flash drives instead. The investigation is carried out by changing the coefficients a, b, and c and analyzing their effects on the properties of the graph.

Over the years we have used advertising to support the site so it can remain free for everyone. Now what does this inverse or opposite stuff mean?

The statistical relationship between the error terms and the regressors plays an important role in determining whether an estimation procedure has desirable sampling properties such as being unbiased and consistent.

This is the main use of Laplace transformations. Although this assumption is not realistic in many settings, dropping it leads to significantly more difficult errors-in-variables models. Since the slope is positive, the line slopes up and to the right.

Locate the x and y intercepts and compare with the solution above. Adjust m and b in the figure and then click on "hide details".

First, it only gives you the solution for one particular set of boundary conditions and parameters, whereas all the above give you general solutions. Then click "show details" and see how close you got. A negative slope goes down to the right. Play with the a slider and observe the results, including negative values.

Now move the rightmost slider for b and let it settle on, say, 5. It can also happen if there is too little data available compared to the number of parameters to be estimated e.Question write the standard form of the equation of the line with slope 0 passing through the point (3,2). Answer by doukungfoo() (Show Source): You can put this solution on YOUR website!

Any line that has a slope of zero is a horizontal line. In a cylindrical coordinate system, 0 ≤ r ≤ R, the diffusion equation has the following form.

[35] The most general initial and boundary conditions for the radial problem are. It is a common to ask to have to convert equation of line from slope intercept to standard form, as demonstrated by the pictures below.

Example of Converting. See also General Function Explorer where you can graph up to three functions of your choice simultaneously using sliders for independent variables as above. Linear functions. Linear functions are those where the independent variable x never has an exponent.

So for example they would not have a var such as 3x 2 in them. The linear function on this page is the general way we write the equation. Differential Equations: some simple examples, including Simple harmonic motionand forced oscillations.

Physclips provides multimedia education in introductory physics (mechanics) at different levels. Modules may be used by teachers, while students may use.
