- TITLE(predict @@ Regression Prediction)
- USAGE(
- predict(reglist, DOTS)
- )
- ARGUMENTS(
- ARG(reglist @@ a list produced by LANG(regress).)
- ARG(DOTS @@ either a series of vectors, all of the same length,
- separated by commas, or a matrix.
- If the former, the vectors contain the
- data for the explanatory variables for which we wish to make predictions.
- If a matrix, then the columns contain the data for the explanatory variables.)
- )
- DESCRIPTION(
- LANG(predict) calculates prediction intervals for regression.
- Returns a matrix, the rows of which correspond to separate predictions at
- different x-values (the number of rows equals the length of the vectors
- in LANG(DOTS), or the number of rows if LANG(DOTS) is a matrix),
- and the columns of which contain the value
- of the prediction, the upper and lower limits for a confidence
- interval for the mean of all responses taken at x,
- and the upper and lower limits of a prediction
- interval for an observation taken at x.
