Chi square test for linear regression
WebFeb 14, 2024 · The formula for the one-sample t-test statistic in linear regression is as follows: t = (m – m0) / SE. Where: t is the t-test statistic. m is the linear slope or the coefficient value obtained using the least square method. m0 is the hypothesized value of linear slope or the coefficient of the predictor variable. WebFeb 8, 2024 · A chi-square fit test for two independent variables: used to compare two variables in a contingency table to check if the data fits A small chi-square value means that data fits. A large chi-square value means that data doesn’t fit. The hypothesis we’re testing is: Null: Variable A and Variable B are independent.
