Amultiple regression model using 200 data points (with three independent variables) has how many degrees of freedom for testing the statistical significance of individual slope coefficients?
196
199
198

196

Step-by-step explanation:

Formula of degree of freedom for simple regression = n-2

Formula of degree of freedom for multiple regression = n-k-1

We are given the case of multiple regression and there are three independent variables.

So, k = 3

n = 200

So, Degree of freedom for multiple regression =

                                                                              =

                                                                              =

So, Option A is true .

Hence degrees of freedom for testing the statistical significance of individual slope coefficients is 196

Recombination is a process by which pieces of DNA are broken and recombined to produce new combinations of alleles. In eukaryotic cells, which are cells with a nucleus and organelles, recombination typically occurs during meiosis. Meiosis is a form of cell division that produces gametes, or egg and sperm cells.When translocation or recombination take place it results in a chromosome that differs from the original. This new chromosome has a mutation, or a change in genetic material. When a mutation occurs and DNA is exchanged between chromosomes, genetic variability is increased.
