Unobserved Variables,hese methods has given rise to many misunderstandings which, we shall argue, often arise because the need for a statistical, or probability, model is unrecognised or disregarded. A statistical model is the bridge between intuition and the analysis of data.

Models for Ability,theory. Maximum likelihood estimation and notions of sufficiency also appear in a central role which is developed in later chapters. A good deal of misunderstanding and controversy has surrounded the Rasch model and we hope some of this may be dispelled by the present approach.

Social Measurement,ing the circumstances under which the simple measures in common use may be used legitimately. Our treatment of the former requires the introduction of the hazard function of a probability function for a positive random variable and the renewal rate, both of which are defined.

Simple Mixtures,en if it is theoretically possible to make the distinction, it may be very difficult to do so in practice. Mixtures of normal and exponential distributions are both common and important and the mathematical simplicity of the latter makes them an ideal vehicle for exploring some of the fundamental issues.

2191-544X of unknown parameters. The form of the distribution may be known, partially or completely, and inferences have to be made on the basis of a sample of observations drawn from the distribution; often, but not necessarily, a random sample. This brief deals with problems where some of the sample members

Measurement, Estimation and Prediction,s is because the quantities to be ‘measured’ turn out to be represented by the parameters or random variables of a statistical model. Measurement then becomes a matter of predicting the values of random variables or of estimating the parameters of a distribution. When the unobserved variables are la
