Step 1: Find out the test static Z is. z = p ^ − p 0 p o ( 1 − p 0) n. Where, p ^ = Sample Proportion. P0 = assumed population proportion in the null hypothesis. N = sample size. Step 2: Look at the Z-table to find the corresponding level of P from the z value obtained.

WebThe lower a feature's p-value is, the greater a chance that the relationship is accurate. Typically p-values below 0.05 (aka 5%) are thought of as good p-values. To make a simple and non-noisy model, we ran an initial regression and then filtered our features to only keep those with low p-values. fbfhghWeb2 days ago · Thanks for contributing an answer to Stack Overflow!
