decomposed into two main subcomponents we care about: error due to "bias" and error due to "variance". There is a tradeoff between a model's ability to minimize bias and variance. Understanding these two types of error can help us error variance definition diagnose model results and avoid the mistake of over- or under-fitting. Bias and Variance error variance psychology Understanding how different sources of error lead to bias and variance helps us improve the data fitting process resulting in
more accurate models. We define bias and variance in three ways: conceptually, graphically and mathematically. Conceptual Definition Error due to Bias: The error due to bias is taken as the difference between the
expected (or average) prediction of our model and the correct value which we are trying to predict. Of course you only have one model so talking about expected or average prediction values might seem a little strange. However, imagine you could repeat the whole model building process more than once: each time you gather new data and run a new analysis creating a new model. Due experimental error variance to randomness in the underlying data sets, the resulting models will have a range of predictions. Bias measures how far off in general these models' predictions are from the correct value. Error due to Variance: The error due to variance is taken as the variability of a model prediction for a given data point. Again, imagine you can repeat the entire model building process multiple times. The variance is how much the predictions for a given point vary between different realizations of the model. Graphical Definition We can create a graphical visualization of bias and variance using a bulls-eye diagram. Imagine that the center of the target is a model that perfectly predicts the correct values. As we move away from the bulls-eye, our predictions get worse and worse. Imagine we can repeat our entire model building process to get a number of separate hits on the target. Each hit represents an individual realization of our model, given the chance variability in the training data we gather. Sometimes we will get a good distribution of training data so we predict very well and we are close to the bulls-eye, while sometimes our training data might be full o

This week’s question is from a reader who wants an explanation of the "bias vs. variance tradeoff in statistical learning.” Q: Explain the bias vs. variance tradeoff in statistical learning. A: The bias-variance tradeoff is an important aspect of data science projects based on machine learning. To simplify the discussion, let me provide an explanation of the tradeoff that avoids mathematical equations. To approximate reality, learning algorithm use mathematical or statistical models whose “error” can be split into two main components: reducible and irreducible error. Irreducible error or inherent uncertainty is associated with a natural variability in a system. On the other hand, reducible error, as the name suggests, can be and should be minimized further to maximize accuracy. Reducibl
entrance test scores for each subpopulation have equal variance. We denote the value of this common variance as σ2. That is, σ2 quantifies how much the responses (y) vary around the (unknown) mean population regression line https://onlinecourses.science.psu.edu/stat501/node/254 \(\mu_Y=E(Y)=\beta_0 + \beta_1x\). Why should we care about σ2? The answer to this question http://stats.stackexchange.com/questions/22422/how-to-conceptualize-error-in-a-regression-model pertains to the most common use of an estimated regression line, namely predicting some future response. Suppose you have two brands (A and B) of thermometers, and each brand offers a Celsius thermometer and a Fahrenheit thermometer. You measure the temperature in Celsius and Fahrenheit using each brand of thermometer on ten different days. Based on the resulting error variance data, you obtain two estimated regression lines — one for brand A and one for brand B. You plan to use the estimated regression lines to predict the temperature in Fahrenheit based on the temperature in Celsius. Will this thermometer brand (A) yield more precise future predictions …? … or this one (B)? As the two plots illustrate, the Fahrenheit responses for the brand B thermometer don't deviate as far from the estimated error due to regression equation as they do for the brand A thermometer. If we use the brand B estimated line to predict the Fahrenheit temperature, our prediction should never really be too far off from the actual observed Fahrenheit temperature. On the other hand, predictions of the Fahrenheit temperatures using the brand A thermometer can deviate quite a bit from the actual observed Fahrenheit temperature. Therefore, the brand B thermometer should yield more precise future predictions than the brand A thermometer. To get an idea, therefore, of how precise future predictions would be, we need to know how much the responses (y) vary around the (unknown) mean population regression line \(\mu_Y=E(Y)=\beta_0 + \beta_1x\). As stated earlier, σ2 quantifies this variance in the responses. Will we ever know this value σ2? No! Because σ2 is a population parameter, we will rarely know its true value. The best we can do is estimate it! To understand the formula for the estimate of σ2 in the simple linear regression setting, it is helpful to recall the formula for the estimate of the variance of the responses, σ2, when there is only one population. The following is a plot of the (one) population of IQ measurements. As the plot suggests, the average of the IQ measurements in the population is 100. But, h

Namely, the idea that the error (epsilon), as well as any other sort of variance, applies only (so I thought) to a group (a sample or whole population). Now, we're being taught that one of the regression assumptions is that the variance is "the same for all individuals". This is somehow shocking to me. I always thought that it was the variance in Y accross all values of X that was assumed to be constant. I had a chat with the prof, who told me that when we do a regression, we assume our model to be true. And I think that's the tricky part. To me, the error term (epsilon) always meant something like "whatever elements we don't know and that might affect our outcome variable, plus some measurement error". In the way the class is taught, there's no such thing as "other stuff"; our model is assumed to be true and complete. This means that all residual variation has to be thought of as a product of measurement error (thus, measuring an individual 20 times would bNo related pages.

A Windows error is an error that happens when an unexpected condition occurs or when a desired operation has failed. When you have an error in Windows, it may be critical and cause your programs to freeze and crash or it may be seemingly harmless yet annoying.
A stop error screen or bug check screen, commonly called a blue screen of death (also known as a BSoD, bluescreen), is caused by a fatal system error and is the error screen displayed by the Microsoft Windows family of operating systems upon encountering a critical error, of a non-recoverable nature, that causes the system to "crash".
One of the biggest causes of DLL's becoming corrupt/damaged is the practice of constantly installing and uninstalling programs. This often means that DLL's will get overwritten by newer versions when a new program is installed, for example. This causes problems for those applications and programs that still need the old version to operate. Thus, the program begins to malfunction and crash.
Computer hanging or freezing occurs when either a program or the whole system ceases to respond to inputs. In the most commonly encountered scenario, a program freezes and all windows belonging to the frozen program become static. Almost always, the only way to recover from a system freeze is to reboot the machine, usually by power cycling with an on/off or reset button.
Once your computer has been infected with a virus, it's no longer the same. After removing it with your anti-virus software, you're often left with lingering side-effects. Technically, your computer might no longer be infected, but that doesn't mean it's error-free. Even simply removing a virus can actually harm your system.
