A prediction error-based hypothesis testing method …

There are different ways of doing statistics. The technique used by the vast majority of biologists, and the technique that most of this handbook describes, is sometimes called "frequentist" or "classical" statistics. It involves testing a null hypothesis by comparing the data you observe in your experiment with the predictions of a null hypothesis. You estimate what the probability would be of obtaining the observed results, or something more extreme, if the null hypothesis were true. If this estimated probability (the P value) is small enough (below the significance value), then you conclude that it is unlikely that the null hypothesis is true; you reject the null hypothesis and accept an alternative hypothesis.

Root Mean Square Error (RMSE) is the standard deviation of the (prediction errors). Residuals are a measure of how far from the regression line data points are; RMSE is a measure of how spread out these residuals are. In other words, it tells you how concentrated the data is around the . Root mean square error is commonly used in climatology, forecasting, and to verify experimental results.

Concept Learning The problem of inducing general functions from specific training examples is central to learning. Concept learning acquires the definition of a general category given a sample of positive and negative training examples of the category, the method of which is the problem of searching through a hypothesis space for a hypothesis that best fits a given set of training examples. A hypothesis space, in turn, is a predefined space of potential hypotheses, often implicitly defined by the hypothesis representation. Learning a Function from Examples Given: Idea: to extrapolate observed y's over all X. Hope: to predict well on future y's given x's. Require: there must be regularities to be found!

The significance level you choose should also depend on how likely you think it is that your alternative hypothesis will be true, a prediction that you make before you do the experiment. This is the foundation of Bayesian statistics, as explained below.

Again, one reason that small standard errorsare desirable is that sample statistics more accurately represent populationstatistics when the standard error is small.

Given below are some of the terms used in hypothesis testing: 1

Second,and more importantly for hypothesis testing, the smaller the sampling error,the easier it is to conclude that the sample statistic represents a differentpopulation.

Understanding Hypothesis Tests: Confidence Intervals …


Originally developed by C.E. Shannon in the 1940s for describing bounds on information rates across telecommunication channels, information and coding theory is now employed in a large number of disciplines for modeling and analysis of problems that are statistical in nature. This course provides a general introduction to the field. Main topics include entropy, error correcting codes, source coding, data compression. Of special interest will be the connection to problems in pattern recognition. Includes a number of projects relevant to neuroscience, cognitive and linguistic sciences, and computer vision. Prerequisites: High school algebra, calculus. MATLAB or other computer experience helpful. Prior exposure to probability theory/statistics helpful.

In other words, we simply take out the word "positive", which implies the direction of our effect. In our example, making a two-tailed prediction may seem strange. After all, it would be logical to expect that "extra" tuition (going to seminar classes as well as lectures) would either have a positive effect on students' performance or no effect at all, but certainly not a negative effect. However, this is just our opinion (and hope) and certainly does not mean that we will get the effect we expect. Generally speaking, making a one-tail prediction (i.e., and testing for it this way) is frowned upon as it usually reflects the hope of a researcher rather than any certainty that it will happen. Notable exceptions to this rule are when there is only one possible way in which a change could occur. This can happen, for example, when biological activity/presence in measured. That is, a protein might be "dormant" and the stimulus you are using can only possibly "wake it up" (i.e., it cannot possibly reduce the activity of a "dormant" protein). In addition, for some statistical tests, one-tailed tests are not possible.
