Question

Which of the following is untrue about Prediction Using Discriminant Analysis for Gene Prediction?

(a) QDA draws a curved line based on a quadratic function

(b) LDA works by drawing a diagonal line that best separates coding signals from noncoding signals based on knowledge learned from training data sets of known gene structures

(c) Some gene prediction algorithms rely on discriminant analysis, either LDA or quadratic discriminant analysis (QDA), to improve accuracy

(d) LDA works by plotting a three-dimensional graph of coding signals versus all potential 3’ splice site positions

I have been asked this question in an interview for job.

I would like to ask this question from Gene Prediction in Eukaryotes in division Gene and Promoter Prediction of Bioinformatics

Answer 1

Right option is (d) LDA works by plotting a three-dimensional graph of coding signals versus all potential 3’ splice site positions

Explanation: QDA draws a curved line based on a quadratic function instead of drawing a straight line to separate coding and noncoding features. This strategy is designed to be more flexible and provide a more optimal separation between the data points.
