Nettet3. feb. 2024 · For example, for y with size 100,000 x 1 and x of size 100,000 x 3 it is possible to do this: [b,int,r,rint,stats] = regress (y,x); predicted = x * b; However, this does not account for the fact that the the columns in x may require different weighting to produce optimal outcomes, eg does not produce weightings for b. NettetIn statistics, the term linear model is used in different ways according to the context. The most common occurrence is in connection with regression models and the term is often taken as synonymous with linear regression model. However, the term is also used in time series analysis with a different meaning. In each case, the designation "linear" is …
