For a Gaussian discriminant classifier, where you model P(y = 1) (using a binomial) and P(x|y = 0) and P(x|y = 1). The latter have distinct means µ0 and µ1, and a shared covariance matrix Σ . If we classify an example for which we know inputs x1, . . . xn−1, but the value of xn is missing.  The value of xn is filled by its class-conditional means, E(xn|y = 0) and E(xn|y = 1). Using the log-odds ratio, can someone provide a mathematical justification

The grade point average of the students at UTC is 2.80 with a standard deviation of 0.84. The grade point average of students at UTK is 2.4 with a standard deviation of 0.84. Which university shows a more dispersed grade distribution?

A mathematics teacher recorded the length of time, y minutes, taken to travel to school when leaving home x minutes after 7 am on seven selected mornings. The results are as follows. x 0 10 20 30 40 50 60 y 16 27 28 39 49 48 51 a. plot the data on scatter diagram b. (i) calculate the equation of the least squares regression line of y on x, writing your answer in the form y = a + bc (ii) draw the regression line on your scatter diagram c. the mathematics teacher needs to arrive at school no […]

In an opinion poll, each individual in a random sample of 275 individuals from a large population is asked which political party he/she supports. If 45% of the population support party A, calculate (approximately) the probability that at least 116 of the sample support A.

early in 2007 consumer reports published the reuslts of an extensive investigation of broiler chickens purchased from food stores in 23 states. tests for bacteria in the meat showed that 81% of the chickens were contaminated with campylobacter, 15% with salmonella, and 13% with both. What’s the probability that a tested chicken was not contaminated with either kind of bacteria?
