Hello,
The error comes from NAs where you would expect coefficients. Try the
following.
set.seed(7511) # Make the example reproducible
N - 100
Time -1:N
Price - rnorm(N, 8, 2)
estim - numeric(N) # It's better
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
Hello,
