• Apr 12, 2018 · My student asked today how to interpret the AIC (Akaike’s Information Criteria) statistic for model selection. We ended up bashing out some R code to demonstrate how to calculate the AIC for a simple GLM (general linear model). I always think if you can understand the derivation of a statistic, it is much easier to remember how to use it.
In order to actually be usable in practice, the model should conform to the assumptions of linear regression. Assumption 1 The regression model is linear in parameters. An example of model equation that is linear in parameters Y = a + (β1*X1) + (β2*X2 2) Though, the X2 is raised to power 2, the equation is still linear in beta parameters. So ...
  • To perform the repeated-measures ANOVA in SPSS, click on Analyze, then General Linear Model, and then Repeated Measures. See Figure 7-2. Figure 7-2 Select Analyze, General Linear Model, Repeated Measures In the resulting Repeated Measures dialog, you must specify the number of factors and the number of levels for each factor.
  • In the SPSS output, Pearson chi-square, likelihood-ratio chi-square, and linear-by-linear association chi-square are displayed. Fisher's exact test and Yates' corrected chi-square are computed for 2x2 tables. State the null and alternative hypothesis that is being tested.
  • • Interpretation: Boys were 31% more likely to die from leukemia compared to girls. • Substituting: 1254052 / 16430824 = 0.76 • Interpretation: Compared to boys, girls were 24% (1-0.76) less likely to die. • Based on these results, can we conclude that there is a statistically significant difference in mortality by sex of
For simple linear regression, the MSM (mean square model) = (i - )²/(1) = SSM/DFM, since the simple linear regression model has one explanatory variable x. The corresponding MSE (mean square error) = ( y i - i )²/( n - 2) = SSE/DFE , the estimate of the variance about the population regression line ( ²).

Under the general linear model, the probability of observation yidepends on the parameters β and σ2, and can be written P(yi;β,σ2). 2. Because the observations are independent, the probability of the complete set of data y is the product of the probabilities of its individual observations: P(y;β,σ2)= YN i=1. General Linear Model->Multivariate. NOTE: The Simple Scatter plot is used to estimate the relationship between two variables.. Note: The default behaviour in SPSS Statistics is for the last category (numerically) to be selected as the reference category. Pisces horoscope for tomorrow by astrotwins
