Introduction to bivariate analysis - Statistics

Introduction to bivariate analysis When one measurement is made on each observation,univariateanalysisis more than one measurement is made on each observation,multivariate analysisis this section, we focus onbivariate analysis , where exactly twomeasurements are made on each two measurements will be calledXandY. SinceXandYare obtained for each observation, the data for one observationis the pair (X, Y). bivariate data can be stored in a table with two columns:X YObs. 12 1 Obs. 24 4 Obs. 33 1 Obs. 47 5 Obs. 55 6 Obs. 62 1 Obs. 74 4 Obs. 83 1 Obs. 97 5 Obs. 105 6 Some examples: Height (X) and weight (Y) are measured for each individ-ual in a sample. Stock market valuation (X) and quarterly corporate earn-ings (Y) are recorded for each company in a sample. A cell culture is treated with varying concentrations of adrug, and the growth rate (X) and drug concentration(Y) are recorded for each trial.

Introduction to bivariate analysis • When one measurement is made on each observation, univariate analysis is applied. If more than one measurement is made on each observation,

1 Sampling from discrete distributions

2 Sampling from continuous distributions Continuous random variables are (informally) those whose sample space is composed of real intervals not exclusively containing integers. In a continuous distribution the prob-ability of taking on any particular value in the sample space in 0; probabilities can only be

3 Importance Sampling when the target density is unnormalized A function is a probability density on the interval I if the function is non-negative and in- tegrates to 1 over I.

3. Conditional probability & independence Conditional Probabilities • Question: How should we modify P(E) if we learn that event F has occurred? • Derivation: Suppose we repeat the experiment n times. Let n(E ∩ F) be the number of times that both E and F occur, and n(F) the number of times F occurs. • The proportion of times E occurs only counting trials where F occurs is
