WebbImplementation of the two-way fixed effects (TWFE) estimator in R is quite simple using the cutting edge felm() function from the “lfe” package. While R users have traditionally estimated panel data models with the plm() function, this is now considered antiquated amongst most working applied econometricians using R. WebbA “failure effect” is the result of a failure mode on the product or system function as perceived by the user. Failure effects can be described in terms of what the end user may see or experience. The study of consequences of identified failures is called effects analysis.
