What is a good prediction error?

Ideally, this value should be close to zero, which means that your predictor is close to the true value. The concept is similar to Mean Squared Error (MSE), which is a measure of the how well an estimator measures a parameter (or how close a regression line is to a set of points).

Prediction error quantifies one of two things:

In regression analysis, it’s a measure of how well the model predicts the response variable. In classification (machine learning), it’s a measure of how well samples are classified to the correct category. Sometimes, the term is used informally to mean exactly what it means in plain English (you’ve made some predictions, and there are some errors). In regression, the term “prediction error” and “Residuals” are sometimes used synonymously. Therefore, check the author’s intent before assuming they mean something specific (like the mean squared prediction error).

Mean Squared Prediction Error (MSPE)

MSPE summarizes the predictive ability of a model. Ideally, this value should be close to zero, which means that your predictor is close to the true value. The concept is similar to Mean Squared Error (MSE), which is a measure of the how well an estimator measures a parameter (or how close a regression line is to a set of points). The difference is that while MSE measures of an estimator’s fit, the MSPE is a measure of a predictor’s fit— or how well it predicts the true value.

Quantifying Prediction Errors

Prediction error can be quantified in several ways, depending on where you’re using it. In general, you can analyze the behavior of prediction error with bias and variance (Johari, n.d.). In statistics, the root-mean-square error (RMSE) aggregates the magnitudes of prediction errors. The Rao-Blackwell theory can estimate prediction error as well as improve the efficiency of initial estimators. In machine learning, Cross-validation (CV) assesses prediction error and trains the prediction rule. A second method, the bootstrap, begins by estimating the prediction rule’s sampling distribution (or the sampling distribution’s parameters); It can also quantify prediction error and other aspects of the prediction rule.

Topspin groundstrokes, volleys, overheads and serves will be covered with a combination of ball-fed drills and structured rally drills. 3.0 – 3.5 Intermediate: This player can maintain a rally from the baseline with basic sound stoke technique. We will introduce more advanced mechanics and strategies for each stroke to create more ball control, consistency and power. Ball-fed, structured rally, and live ball drills will be utilized. 3.5 – 4.0 Advanced Intermediate: This player can consistently maintain a rally with pace and has a more advanced knowledge of the game. Our focus will be on strengthening the player’s basic stroke mechanics and shot patterns as well as your approach and passing shots, drop shots, return of serve. 4.0 – 4.5 Advanced: This player has an overall understanding of the game and can hit fair amount of power, control and/or consistency. The drill class will give participants the opportunity to get a great tennis workout and lots shots. We utilize will be live ball, and strategy-based games with friendly competition. These are high energy, fast-paced clinics.
