Reliability of the model created by RSM (Response Surface Methodology)?

23 January 2021 1 549 Report

When you create a model with RSM, even if the R2 value is large and the result of the analysis of variance is significant, if you look at the individual explanatory variables, if there are many variables that are not significant, is the model unreliable?

I built a model to predict the strength of the alloy from arbitrary fabrication conditions.

The R2 value was 0.78 and the p-value in the analysis of variance for the model was 0.0040, but p > 0.05 for 7 of the 9 explanatory variables.

Can random sampling have inclusion criteria?

As random sampling means that everyone in the population have an equal chance to be chosen, can it have inclusion criteria? My research participants have been chosen based on the inclusion...

How do historians determine the credibility sources in modern history?

For a source to be considered reliable it must contain accurate historical information. But how does one determine the accuracy and reliability of sources in modern and recent history since not...

Can two EC50 values with different hill slopes be compared?

Hello, I fit a classical dose response curve Y=Bottom + (Top-Bottom)/(1+10^((LogEC-X)*HillSlope)) to my data (not related to inhibitors etc). The model I use is purely qualitative but it fits...

Physical-chemical formation of stalactites/stalagmites. what promotes the formation/growth of these structures?

I know, or think I do, the basic idea behind these natural structures, as from what I know they form due to water dripping from the top leaving a salt deposit behind. But started to wonder about...

Is there an ideal incubation time of RGO-modified SPCE before subsequent use, i.e., electrochemical characterization or further modification?

I notice that upon washing and air-drying of my RGO/SPCE surface and characterizing again via DPV, the current response towards ferricyanide probe significantly decreases. My worry is that the...

How to assure whether a regression tree overfit or not by seeing bias-variance value of the model?

Lets consider a regression tree in which variance is 1.1065*e-10 and bias is 2.962e-13. Also the model RMSE on training set is 1.5e-5 and on training set is 1.2950e-5. Is the model is overfit or...
