What technique do I use to justify eliminating measurements at a specific timepoint in a series?I have measurements of an attribute at initial, 2hr, 4hr, 6hr. I want to drop the 4hr measurements because it does not add much value to the business application. The measurements exhibit a negative slope from initial to final... What technique or rationale might I use to justify eliminating the 4hr measurement? [I was thinking along the lines of Information Gain, but I admit I don't know much about it beyond the context of Decision Trees]. I appreciate any guidance.
AnalyticsRe: What technique do I use to justify eliminating measurements at a specific timepoint in a series?IMO the technique or rationale is not a statistical methods question but one driven by knowledge of the process, data, and problem at hand. If the 4th data point adds no value, and eliminating it is not unethical or against some application accepted standard or process rationale...then just use the JMP exclude/hide capability to eliminate those observations from any analysis or reports.
