This function performs the background sensitivity interval calculation for the OLS estimator in a regression model.
sensOLS(delta1, df, est, se, alpha = 0.05, talpha)A numeric vector of values of the first sensitivity parameter. Default
value seq(-.1, .1, .01). Not used for 2SLS estimator.
Degrees of freedom of the model; 2SLS estimate and its standard error.
Significance level. Default at 0.05.
If the interval is to be adjested for model selection etc, the multiplicative factor to be used. Optional.
Returns an object of class "si".
An object if class "si" is essentially a matrix of two columns for the the upper and lower sensitivity limits corresponding to the sensitivity parameters.
See the description of senslm.
