Regression Analysis

Please find a REGRESSION ANALYSIS for this… If a regression analysis was to be completed on body mass index (BMI), what could be an independent variable in that analysis? Why? If we could, what other independent variables should be included in the analysis? What statistic(s) would show the value of that regression in understanding BMI? Alternatively, find an article that uses regression analysis to study […]

Respond to Dianne’s Hypothesis

My hypothesis test is whether using a pain reliever, Pyridium (phenazopyridine), before a in office cystoscopy decreases the burning/pain sensation after the procedure.   A cystoscopy is where a telescope is inserted through the urethra into the bladder.  We do this procedure for many reasons including blood in the urine, bladder cancer surveillance and recurrent urinary tract infections.   Two types of hypotheses are the hypothesis and […]
