- 1response variablethe variable X
- 2analysis of variancethe tecnique that allows statistics practioners to compare two or more populations of intereval data, and determine if differences exist between two or more population means
- 3responsesvalues of the X variable
- 4experimental unitthe unit that we measure
- 5factorthe criteria which by which we classify the populations
- 6factor leveleach populations is one
- 7multinomial experiment properties- the experiment consists of a fixed number of trials (n)
the outcome of each can be classified into k categories, called cells
probability p(i), that the outcome will fall into cell i constant to each trial
- each trial of the experiment is independent of the other trials - 8chi-squared test of a contingency table- used to determine whether there is enough evidence to infer that the two nominal variables are related, and to infer that the two nominal variables are related, and to infer that differences exist between two or more populations of nominal data
- 9Chi Squares Test of a Contingency Table HypothesesHo- The two variables are independent
H1- The two variables are dependent - 10chi squared goodness of fit testwhen we compare the observed sample distribution with the expected probability distribution
- 11multinomial experimentextension of the binomial experiment, where two or more possible outcomes per trial
- 12Sum of Squares for Errormeasure of the amount of variation in the response variable not caused by the treatements (within-treatments variation_
- 13Sum of Squares for Treatmentsmeasures the proximity of the sample means to each other (between treatments variation)
- 14Segmentation Theory- securities are divided into market segments by the various financial institutions investing in the market
- - 15Expectatations Hypothesis- explains the yields on long-term securities as a function of the short-term rates
- explains the shape and movement of the yield curve - 16YIeld Curve- known as the term structure of interest rates
- interest rate at a specific time for all securities having equal risk but differing maturity dates - 17Liquidity Premium theory- the long-term rates should be higher than the short term rates
- 18Normal Yield Curve- upward sloping
