I have used matlab method crossvalind to create 70-30 ratio of training and testing and did this 5 times. Finally I calculated the average over the five runs. Brief discussion about Linear Regression Classifier I have a legacy system I need to update with the exact equivalent of Matlabs Linear Regression function as calculated with the "\" i.e. the backslash operator. Precision is critically important. Ideally I'd like to see the Matlab code so I can re-rewrite it in the target legacy language.

For example, fit a linear model to data constructed with two out of five predictors not present and with no intercept term: This MATLAB function returns a vector b of coefficient estimates for a multiple linear regression of the responses in vector y on the predictors in matrix X. In general, a linear regression model can be a model of the form where f (.) is a scalar-valued function of the independent variables, Xij s. The functions, f (X), might be in any form including nonlinear functions or polynomials. The linearity, in the linear regression models, refers to the linearity of the coefficients βk.

However, when I have the data plotted in a log-log scaled graph (both axes in logarithmic scale) the linear fit does not appear to me to be linear. How can I perform a linear regression in a log-log graph with Matlab. I have attached a picture of the graph and the linear fitting that I obtained. Any help is much appreciated! Thank you in advance!

Hello, this is my matlab script that is supposed to take data from an excel spread sheet and use it to create a y = mx+b function by linear regression. Here is my code and attached is the excel spread sheet. The first row is the amount in gallons and the next two rows are the amount of time it took to move the gallons in seconds.

y = kx + b. Is that possible in MatLab?

Confidence intervals provide a measure of precision for linear regression coefficient estimates. A 1 0 0 (1-α) % confidence interval gives the range the corresponding regression coefficient will be in with 1 0 0 (1-α) % confidence. You can also change the confidence level. Find the 99% confidence intervals for the coefficients.

There are two sets of data: one for O2 and one for Heat. I made a linear regression in the plot of those two data sets which gives me an equation of the form O2 = a*Heat +b. So now I need to find the confidance interval of a. That for I need to find the standard deviation of a which I somehow just can't find out how to get it.
