LPR Model
LatestPollResults.com is an unbiased, statistically-based probability model used to analyze the U.S general elections. From the Latest Poll Results for each race, the mathematical probability of winning is calculated for both the Democratic and Republican candidates. A candidate's lead is considered statistically significant if the probability of winning is at least 97.5%. In this case, the candidate is considered "safe" for that race. If a candidate's lead is not statistically significant, then the race is considered a "toss-up". LPR calculates all possible outcomes from the "toss-up" races and calculates the probability of each possible outcome.
