Hi all, I am trying to perform some analysis on the residuals of pair-wise linear regressions between two large sets A with dimensions {k x m}, and B {k x n} . So I need to regress every column B[,j] of B on every column A[,i] of A and produce a matrix C with dimensions {m x n}, so that C[i,j] contains the z-score of the k-th (last) residual of the aforementioned linear regression. I...

Dear R Users, I am attempting to use the strucchange package but get an error which is difficult to decipher.

Hello, Some context:  let's say I have a data series (let's call it PRICE, for simplicity), sample size N.  I have a desire to regress that on TIME, and then to use the TIME and intercept coefficients to predict the price in the next period and to use the standard error to calculate a confidence interval.  This is all very easy. However, what I need help for is to calculate a confidence interval for each point in time:  imagin...

Dear R-experts, I guess I have a problem with my fast function (fast tau estimator) here below. Indeed, zero errors look highly suspicious. I guess there is a bug in my R code.

Hello Could you please suggest a way to find out the r square values for each independent variable while using "lm" for developing a multiple linear regression model. Thank you avneet "I have no data yet. It is a capital mistake to theorize before one has data. Insensibly one begins to twist facts to suit theories instead of theories to suit facts." ~ Sir Arthur Conan Doyle (1859-1930), Sherlock Holmes
