A latentvariablemodel is a statistical model that relates a set of Variable mathematics variables so called manifest variables to a set of latentvariable s. It is assumed that 1 the responses on the indicators or manifest variables are the result of an individual s position on the latentvariable s , and 2 that the manifest variables have nothing in common after controlling for the latentvariable local independence . Different types of the latentvariablemodel can be grouped according to whether the manifest and latent variables are categorical or continuous ref David J.

In factor analysis and latent trait analysis the latent variables are treated as continuous normal distribution normally distributed variables, and in latent profile analysis and latent class analysis as from a multinomial distribution . The manifest variables in factor analysis and latent profile analysis are continuous and in most cases, their conditional distribution given the latent variables is assumed to be normal.

In the law of the sale of property both real estate and personal property or chattels a latent defect is a fault in the property that could not have been discovered by a reasonably thorough inspection before the sale. The general law of the sale of property is caveat emptor let the buyer beware and buyers are under a general duty to inspect their purchase before taking Possession law possession . However, it is understood at law that inspection is not often sufficient to detect certain deficiencies in the product that can only be discovered through destructive testing or other means that a seller could not reasonably be expected to allow under normal conditions. For example, wood beams and interior brickwork often cannot be fully assessed without destructive testing, and it would be unreasonable for the seller to allow the buyer to take apart a car s engine. As such, the law expects that buyers will protect themselves in the sales contract against defects they cannot possibly be expected to assess prior to purchase. As such, the term latent defect is often used as part of the guarantee clauses in a sales contract so that the buyer can recover damages from the seller if defects turn up in the property after the sale. For example, the seller may be required to pay for repairs of any such damage. There is no automatic right for a buyer to claim against a seller for such latent defects when they are discovered, absent an agreement in contract. However, if a latent defect is discovered, there is often a presumption against the seller when a claim is made in misrepresentation that the seller knew about the latent defect. As such, the seller is required to show that he or she could ... 23 index.html Latent Defects Insurance http www.blpinsurance.com Latent Defects Insurance http www.qanw.co.uk latentdefects.html Latent Defects Insurance http www.theovalgroup.com latentdefects Latent Defects Insurance Category Tort law Category Real property law Category Personal property law ... more details

inline date July 2010 Latent learning is a form of learning that is not immediately expressed in an overt response it occurs without obvious reinforcement to be applied later. http www.psybox.com web dictionary Latentlearning.htm Latent learning is when an organism learns a new concept in its life, however, the knowledge is not immediately expressed. Instead, it remains dormant, and may not be available to consciousness , until specific events experiences might need this knowledge to be demonstrated. For instance a child may observe a parent setting the table or tightening a screw, but does not act on this learning for a year then he finds out later on that he knows how to do these. In a classical experiment, Tolman and C.H. Honzik 1930 placed three groups of rats in Mazes Mazes in science experiments mazes and observed their behavior each day for more than two weeks. The rats in Group 1 always found food at the end of the maze the rats in Group 2 never found food and the rats in Group 3 found no food for 10 days, but then received food on the eleventh. The Group 1 rats quickly learned to rush to the end of the maze to find their food Group 2 rats did not learn to go to the end Group 3 acted as the Group 2 rats until food was introduced on Day 11. Then they quickly learned to run to the end of the maze and did as well as the Group 1 rats by the next day. References Carol Tavris Carole Wade, Psychology in Perspective Third Edition .

inline date July 2010 An intervening variable is a hypothetical internal state that is used to explain relationships between observed variables, such as independent and dependent variables, in empirical research . History The term intervening variable was first used by behavioral psychologist Edward C. Tolman in 1938. Relation to operational definitions An intervening variable facilitates a better understanding of the relationship between the independent and dependent variables when the variables appear to not have a definite connection. They are studied by means of operational definitions and have no existence apart. For example, an independent variable in a study on latent learning in rats is the number of practice trials received. Each rat receives an increasing number of trials, as one trial is given per day. The dependent variable is the number of wrong turns errors the rats make on a trial. As time, and number of practice trials, increases, the number of errors decreases. Theoretically, an internal state of learning intervened between the independent and dependent variables. It was this state that caused the errors to decrease, not the practice trials. Other examples of intervening variables include motivation, intelligence, intention, and expectation. Intervening variables and circular reasoning As explanations of behavior, intervening variables can lead to an error in logic called circular reasoning . To avoid circular reasoning , two or more operational definitions of the same internal state must be present, and they must be correlated.
