Suppeon that we want to build a model that predicts the group memberhip of a hurricane, other tropical (0) or non-tropical (!) based on the latitude of formation of the hurricane. The response variable is the binary variable Type. new (type of hurricane ) and the predictor variable is First Lat (First Latitude). Using R. we build a model by applying the gim(] function. For the logistic regression model, we specify family = "binomial". The date is available at hepawuserpure bu-berlin de/boga/200 2010 dats meta humansthis.

III onlyIn normality test, it is possible to use a significant test comparing the sample distribution to a normal one in order to ascertain whether data show or not a serious deviation from normality. One of these methods used for normality test is Shapiro-Wilk's test. Which of the following is the correct hypotheses for normality test? Ho: Sample distribution is normal. 3. #1: Sample distribution is non - normal. Ho: Sample distribution is non - normal. b. H: Sample distribution is normal. Ho: Sample has a normal distribution. " H, : Sample has a non - normal distribution. Ho: Sample has a non - normal distribution. d. H: Sample has a normal distribution.In ANCOVA, which of the following R code(s) can be used to test for assumptions? a. lm () b. ggnorm ( ) c. plot (density () ) d. All of the above
