**How to find the Linear Regression? MATLAB Answers**

6/10/2011Â Â· I introduce how to graph a line in slope intercept form. I also discuss graphing vertical and horizontal lines. Please check out my other lessons about Linear Functions:... In this case we find that the differences between the predicted y values and the real y values of line 1 have different signs, which means that if line 2 was long enough there would exist an intersection.

**Error in the intercept MATLAB Answers - MATLAB Central**

I need to fix the intercept (say q, in the expression y=m*x + q) but I do not find the way to do it. Polyfit gives you both m and q, but does not allow you to impose either of the coefficients. Do you knok how I could do that? Thanks, Carlo Antonini... Since your intercept is just the first data points, this is very easy:. . . semilogy(x,ccdf) % CCDF of data hold on plot(x(1), ccdf(1), '*r') Hmmm well actually I guess that depends on what you mean by intercept.

## How To Find Y Intercept In Matlab

### I have 5 data points plotted on a log-log scale, and I want to find a linear regression equation for it. The original (un-logged) equation I'm trying to find is in the form m=k*P^n. Plotting the data on a log-log scale makes it linear so I just need the slope and y-intercept to get the original equation (where k is the y-int and n is the slope). I forgot how to do this.

- This will graph the function for âˆ’10 â‰¤ x â‰¤ 10, find its zero (from the graph, between 0 and 1), find the x and y coordinates of the minimum and integrate the function from the x-intercept to x = 10.

- To get the y intercept of the 2nd line you just need to solve for y=mx+b using your point (x,y) yInt = -perpSlope * x + y; Now you've got the two linear equations and you need to find â€¦
- I fitted the data using the fminsearch. I am able to find the slope and intercept of the fitted equation but, how to find the Linear Regression (R2) value of the fitted equation?
