If I want to estimate the regression of a model by using OLS on Eveiws , and I chose the "keep it as general as possible" approach, what tests can I apply through the estimation and inference process to validate the model and the variables?

Assume that you want to predict Company Performance based on the linear effects of Trust and Commitment that exist among a company’s employees c) If you want to test whether there is a linear effect of Commitment and a curvilinear effect of Trust on Company Performance—such that Company Performance increases up to a certain level of Trust, after which Company Performance diminishes with increasing Trust levels—how would your regression equation look like? Further, explain your answer in your own words. Provide at least two sentences of explanation, in addition to giving the regression equation.
Let's consider a situation where a company wants to understand the relationship between its advertising expenditure and its sales revenue. This is a typical scenario where simple linear regression can be applied. The company hypothesizes that as advertising expenditure increases, sales revenue also increases. To test this hypothesis, the company can collect data on advertising expenditure and sales revenue and perform a simple linear regression analysis. Match the explanatory and response variables with the appropriate information from this description.

The experimenters conducted a regression analysis on the results and made the output from the analysis publicly available on Open Science Framework (osfio/fm5c2). From this output, we can derive that regression equation shown here. The equation predicts participants' relative performance estimates (from 0% to 99%) from their scores on the measure of their theories of intelligence, while controlling their actual scores on the antoymns test. Remember: The theories of intelligence survey includes a series of statements that participants rate on a scale of 1 to 6; average scores on the overall measure range from 1, indicating views of intelligence as highly stable; to 6, indicating views of intelligence as highly changeable. Relative performance estimate = 12.10 (theories of intelligence score) +0.13 (antonyms test score). Based on this regression equation, what kind of regression analysis did the researchers perform? a. A simple linear regression analysis b. Multiple regression analysis…
