WebMar 20, 2024 · I'm trying to understand how to calculate the prediction interval (PI) from a regression model. I want to calculate the PI of specific values not observed in the dataset. I saw that predict can do it with a linear model. What I did in Matlab is. rm=fitlm(X,Y) [ypred,yci] = predict(rm, [10 20]) Based on my data, this gives me Webmdl = fitlm (X,y,modelspec) returns a linear model of the type you specify in modelspec for the responses y, fit to the data matrix X. mdl = fitlm ( ___,Name,Value) returns a linear model with additional options specified by one or more Name,Value pair arguments. For example, you can specify which variables are categorical, perform robust ...
