But severe multicollinearity is a major problem, because it increases the variance of the regression coefficients, making them. The Pearson correlation generates a coefficient called the Pearson correlation coefficient, denoted as r. Linear Regression Assumptions • Assumption 1: Normal Distribution - The dependent variable is normally distributed - The errors of regression equation are normally distributed • Assumption 2: Homoscedasticity - The variance around the regression line is the same for all values of the predictor variable (X). • pwcorr gnp interest inflation, sig star(. 05) The results indicate that although fem appear to be weak instrument, the remaining instruments are probably sufficiently correlated to identified the coefficient on ed. The command spearman takes nearly all the same options as pwcorr (sidak bonferroni print star). However, with asdoc, it is now as easy as A, B, C. Stata is very fast when it needs to perform an operation on the whole column (such as creating a new variable, which we'll do in a second, or running a regression that uses several variables -- which, as you would recognize, involve some matrix operations), and it is painfully slow when you instruct Stata to do operations on single observations.
